Some Properties of Galaxy Structures [PDF]
Open Astronomy, 2011 We analysed some properties of galaxies structures based on the PF catalog of galaxy structures (Panko & Flin 2006) and the Tully NBG catalog (Tully 1988).

Constraining halo properties from galaxy-galaxy lensing and photo-z [PDF]
The Shapes of Galaxies and Their Dark Halos, 2002 Here we present results from a maximum likelihood analysis of galaxy-galaxy weak lensing effects as measured in a 12.5' x 12.5' field obtained at the Nordic Optical Telescope, on La Palma, Spain.

Cosmology with One Galaxy: Autoencoding the Galaxy Properties Manifold
The Astrophysical JournalCosmological simulations like CAMELS and IllustrisTNG characterize hundreds of thousands of galaxies using various internal properties. Previous studies have demonstrated that machine learning can be used to infer the cosmological parameter Ω _m from the

The Properties of Galaxies in Voids [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 We present a comparison of the properties of galaxies in the most underdense regions of the Universe, where the galaxy number density is less than 10% of the mean density, with galaxies from more typical regions.

Dark matter halo properties from galaxy–galaxy lensing★ [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 We present results for a galaxy-galaxy lensing study based on imaging data from the Canada-France-Hawaii Telescope Legacy Survey Wide. From a 12 million object multi-colour catalogue for 124 deg^2 of photometric data in the u*g'r'i'z' filters we compute photometric redshifts (with a scatter of _{ z/(1+z)} = 0.033 and an outlier rate of =2.0 per ...

Characterizing the Conditional Galaxy Property Distribution Using Gaussian Mixture Models
The Astrophysical Journal, 2023 Line-intensity mapping (LIM) is a promising technique to constrain the global distribution of galaxy properties. To combine LIM experiments probing different tracers with traditional galaxy surveys and fully exploit the scientific potential of these ...

The Andromeda Galaxy and Its Star Formation History
Universe, 2023 The state of knowledge of the properties of the Andromeda Galaxy (also known as M31) is reviewed. The spatial structure of the Andromeda Galaxy, its main source populations, and the properties of its gas and dust are discussed.

The DESI PRObabilistic Value-added Bright Galaxy Survey (PROVABGS) Mock Challenge
The Astrophysical Journal, 2023 The PRObabilistic Value-added Bright Galaxy Survey (PROVABGS) catalog will provide measurements of galaxy properties, such as stellar mass ( M _* ), star formation rate (SFR), stellar metallicity ( Z ), and stellar age ( t _age ), for >10 million ...
