11. Kinematics of RR Lyr and HB stars in NGP
ID:
ivo://CDS.VizieR/J/MNRAS/375/1381
Title:
Kinematics of RR Lyr and HB stars in NGP
Short Name:
J/MNRAS/375/1381
Date:
21 Oct 2021
Publisher:
CDS
Description:
Radial velocities and proper motions (derived from the GSC-II data base) are given for 38 RR Lyrae (RRL) stars and 79 blue horizontal branch (BHB) stars in a ~200deg^2^ area around the North Galactic Pole (NGP). Both heliocentric (UVW) and galactocentric (VR, Vphi, Vz) space motions are derived for these stars using a homogeneous distance scale consistent with (m-M)0=18.52 for the Large Magellanic Cloud (LMC).
12. Minislice at the North Galactic Pole. II.

Title:
Minislice at the North Galactic Pole. II.
Short Name:
VII/200
Date:

Publisher:
CDS
Description:
A catalogue of 328 positions, redshifts, bJ magnitudes and bJ-rF colours of galaxies down to bJ=20.5 in 4x0.67 degrees slice close to the North Galactic Pole is presented. Two additional tables containing positions, magnitudes, colours and radial velocities for stars and galaxies not in the main catalogue are also included. The photometry errors are about 0.2 for magnitudes and 0.3 for the colours. The radial velocity errors are estimated as being about 70 km/s. The redshift completeness level of the sample is of the order of ~35% at bj=20.
13. NGP G5-M stars RV, DDO and BV photometry
ID:
ivo://CDS.VizieR/V/103
Title:
NGP G5-M stars RV, DDO and BV photometry
Short Name:
V/103
Date:
21 Oct 2021
Publisher:
CDS
Description:
Radial velocities are given for some 900 stars within 15{deg} of the North Galactic Pole, including almost all such stars classified G5 or latter in the Henry-Draper Catalogue (Cat. <III/135>). Luminosities, two-dimensional spectral classes, composition indices, and distances are derived for the majority of the sample through DDO and BV photometry. The radial velocities come from several instruments (see the "Note(2)" section below) ; the BV and DDO photometries were obtained at Mount Laguna Observatory, with the San Diego State University 24-inch Schmidt reflector.
14. Pioneer 10/11 IPP sky brightness maps
ID:
ivo://CDS.VizieR/J/ApJ/736/119
Title:
Pioneer 10/11 IPP sky brightness maps
Short Name:
J/ApJ/736/119
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present the new constraints on the cosmic optical background (COB) obtained from an analysis of the Pioneer 10/11 Imaging Photopolarimeter (IPP) data. After careful examination of data quality, the usable measurements free from the zodiacal light are integrated into sky maps at the blue (~0.44um) and red (~0.64um) band. Accurate starlight subtraction is achieved by referring to all-sky star catalogs and a Galactic stellar population synthesis model down to 32.0mag. We find that the residual light is separated into two components: one component shows a clear correlation with thermal 100um brightness, while another betrays a constant level in the lowest 100um brightness region. The presence of the second component is significant after all the uncertainties and possible residual light in the Galaxy are taken into account, and thus it most likely has the extragalactic origin (i.e., the COB).
15. Polarization at high galactic latitude
ID:

Title:
Polarization at high galactic latitude
Short Name:
J/A+A/561/A24
Date:
21 Oct 2021
Publisher:
CDS
Description:
We have measured the interstellar polarization for 2400 stars at the distances of up to 600pc and within 60 degrees and 30 degrees from the north and south Galactic poles. These data were used to make interstellar polarization maps of the regions around the north (b>30) and south (b<-60) poles. The new maps give wider and higher resolution views of interstellar polarization at high galactic latitudes and show significant asymmetries in the polarization, one in the northern sky directly across the local spiral and the second between the northern and southern Galactic hemispheres.
16. Polarization catalogue for NGP area
ID:
ivo://CDS.VizieR/J/A+A/372/276
Title:
Polarization catalogue for NGP area
Short Name:
J/A+A/372/276
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present a catalog of interstellar polarization measurements for the North Galactic Pole area (b>70{deg}). Our list contains 336 stars of spectral classes from A to K for which the linear polarization has been measured by us and other researchers. The data are useful for investigation of the distribution of dust, to estimate the amount of interstellar extinction and to map Galactic magnetic field at high galactic latitudes. We discuss also the data selection, sampling and completeness of the catalog.
17. Properties of low z QSO absorption systems
ID:
ivo://CDS.VizieR/J/ApJS/122/355
Title:
Properties of low z QSO absorption systems
Short Name:
J/ApJS/122/355
Date:
21 Oct 2021
Publisher:
CDS
Description:
(Partial): We examine the clustering properties of low-redshift Ly{alpha} and heavy-element QSO absorption line systems seen in the spectra of 13 QSOs at the Galactic poles. This is the densest sample of ~1 degree separated QSOs observed spectroscopically with the Hubble Space Telescope to date. At the median redshift of the Ly{alpha} sample (z{=~}0.7), the QSO lines of sight are separated on transverse scales from about 15 to 200h^-1^Mpc (q_0_=0.5, H=100h.km/s/Mpc), allowing the three-dimensional clustering of the absorbers to be examined on those scales. The Galactic poles are also regions where relatively deep and wide-field galaxy redshift surveys have taken place, so the distributions of galaxies and Ly{alpha} systems can be compared within the same volume of space. There are 545 total absorption lines detected in the complete sample from 13 QSOs. We identify 307 Ly{alpha} systems, of which 18 contain heavy-element lines. We confirm the relatively slow redshift number density evolution for Ly systems at z{<=}1. There are also five likely C IV doublets in our sample, for which the Ly{alpha} line is not accessible.
18. Radial velocities of NGP wide binaries
ID:
ivo://CDS.VizieR/J/AJ/101/625
Title:
Radial velocities of NGP wide binaries
Short Name:
J/AJ/101/625
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present precise radial velocities from a survey of 247 stars centered on Selected Area 57 at the North Galactic Pole, complete for late-type stars with V magnitude brighter than 12.0. The radial velocities have a typical precision of 0.2-0.3km/s. New spectral types and distances estimates are presented for 120 of the stars in the sample. We have considered all pairs of stars with angular separations between 1 and 600arcsec, and find 11 candidate pairs with velocity differences less than 1.5km/s. We estimate that 4 or 5 of the 11 candidate pairs are actually bound binaries, but none with separations larger than 0.1pc. The constraints imposed by these results on the actual distribution of wide binaries in the Galaxy should now be reanalyzed. The unusual precision of our velocities led to the discovery of a new cluster associated with the multiple system ADS 8811 ABC.
19. Radio sources near North Celestial Pole
ID:
ivo://CDS.VizieR/J/AZh/84/387
Title:
Radio sources near North Celestial Pole
Short Name:
J/AZh/84/387
Date:
21 Oct 2021
Publisher:
CDS
Description:
We have used the RATAN-600 radio telescope to study the spectral characteristics of a uniform sample of 504 radio sources from the NVSS catalog (Cat. VIII/65) near the North Celestial Pole at 6 frequencies from 1.1 to 21.7GHz, with the aim of selecting sources possessing inverted spectra near 22GHz, to be included in the program of the RadioAstron future space VLBI mission. We found 17 radio sources with the desired spectral characteristics. Data from spectral studies over a wide wavelength range testify that the spectral behavior of our sample differs from that for a complete sample of sources with the same initial parameters but selected at 20GHz. We find a 6% deficit of inverted-spectrum sources, which can be explained as an effect of the spectral characteristics of "sub-threshold" sources that were not included in the initial sample at 1.4GHz.
20. RIK photometry of far-IR sources in NGP
ID:
ivo://CDS.VizieR/J/MNRAS/401/1587
Title:
RIK photometry of far-IR sources in NGP
Short Name:
J/MNRAS/401/1587
Date:
21 Oct 2021
Publisher:
CDS
Description:
We present follow-up observations of the far-infrared (FIR) sources at 90, 150 and 180um detected as part of the ISOPHOT EBL project, which has recently measured the absolute surface brightness of the cosmic infrared background (CIRB) radiation for the first time independently from COBE data. We have observed the fields at the North Galactic Pole region in the optical and near-IR, and complement these data with Sloan Digital Sky Survey photometry, and spectroscopy where available, and present identifications of the 25 FIR sources which reach down to ~150mJy in all three ISOPHOT bands. Identifications are done by means of full spectral energy density fitting to all sources in the FIR error circle areas.
