Data of figure 1 of the paper, namely the luminosity function of globular clusters in bolometric magnitude. The original HST magnitude is given, then the corresponding...

The selection of the stars of the Tycho program is mainly based on the Tycho input catalogue (TIC), prepared by Egret et al. (1992) from existing ground-based catalogues. The...

We present the results of spectroscopy using HYDRA on the WIYN 3.5m telescope of objects in the deep SWIRE radio field. The goal of the project was to determine spectroscopic...

NGC 253, the Sculptor galaxy, is the southern, massive, star-forming disk galaxy closest to the Milky Way. In this work, we present a new 103-pointing MUSE mosaic of this galaxy...

This catalog contains observed and derived structure parameters for 154 galactic globular clusters, 7 dwarf spheroidal satellites of the Galaxy, and 6 globular clusters in the...

This catalog presents homogeneous photometric parameters of 791 northern bright galaxies based on surface photometry. The observations were made with the 105 Schmidt telescope...

This is an all-sky catalog of 4073 rich clusters of galaxies, each having at least 30 members within the magnitude range m_3_ to m_3_ + 2 (m_3_ is the magnitude of the third...

This is a compendium of 907144 type-I QSOs and AGN, largely complete from the literature to 30 June 2023. 66,026 QSO candidates are also included, calculated via radio/X-ray...

This is a compendium of 829666 type-I QSOs and AGN, largely complete from the literature to 30 April 2021 including SDSS-DR16 quasars and VLASS radio. Also included are 703348...

This is a compendium of 623,004 type-I QSOs and AGN, largely complete from the literature to 15 June 2019 including SDSS-DR15 and LAMOST QSO DR5. Also included are approx 1.32M...

This is a compendium of 607,208 type-I QSOs and AGN, largely complete from the literature to 5-August-2017, including the release of SDSS-DR14. Also included are ~1.35M...

This is a compendium of 452,794 type-I QSOs and AGN, largely complete from the literature to 21 June 2016. Also included are ~900K high-confidence quasar candidates from...

A quasar catalogue is presented with a total of 510764 objects including 424748 type 1 QSOs and 26623 type 1 AGN complete from the literature to 25 January 2015. Also included...

The catalog contains statistically homogeneous and physically well graunded groups of galaxies based on the CfA2 redshift survey (Cat. J/ApJS/121/287) in the area of space...

The Catalog of bright diffuse Galactic nebulae was compiled in the frame of a thesis investigating the spatial distribution and the geometrical properties of bright diffuse...

The Flat Galaxy Catalog (FGC) is the result of a systematic search for disk-like edge-on galaxies with a diameter larger than a=40arcsec and major-to-minor axis ratio a/b>7...

A two-color study of the galaxies detected on POSS-I in a 289deg^2^ region centered on the North Galactic Pole is presented. We use a variety of mapping techniques to...

There is growing evidence that M-dwarf stars suffer radius inflation when compared to theoretical models, suggesting that models are missing some key physics required to...

We present the results from a photometric monitoring program of primarily solar-type open cluster stars obtained during 1994 and 1995. Several members of the {alpha} Persei...

A fine structure related to the kinematic peculiarities of three components of the Scorpius-Centaurus association (LCC = Lower Centaurus-Crux, UCL = Upper Centaurus-Lupus, and...
