The Massive End of the Stellar Mass Function [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We derive average flux corrections to the \texttt{Model} magnitudes of the Sloan Digital Sky Survey (SDSS) galaxies by stacking together mosaics of similar galaxies in bins of stellar mass and concentration.

Stellar coronal mass ejections [PDF]
Serbian Astronomical Journal, 2022 Stellar coronal mass ejections (CMEs) are a growing research field, especially during the past decade. The large number of so far detected exoplanets raises the open question for the CME activity of stars, as CMEs may strongly affect exoplanetary atmospheres.

An HSC view of the CMASS galaxy sample. Halo mass as a function of stellar mass, size and S\'ersic index [PDF]
A&A 622, A30 (2019), 2018 Aims. We wish to determine the distribution of dark matter halo masses as a function of the stellar mass and the stellar mass profile, for massive galaxies in the BOSS CMASS sample. Methods.

Breaking down the link between luminous and dark matter in massive galaxies [PDF]
, 2011 We present a study on the clustering of a stellar mass selected sample of galaxies with stellar masses M*>10^10Msol at redshifts 0 ...

Red Galaxy Growth and the Halo Occupation Distribution [PDF]
Astrophys.J.682:937-963,2008, 2008 We have traced the past 7 Gyr of red galaxy stellar mass growth within dark matter halos. We have determined the halo occupation distribution, which describes how galaxies reside within dark matter halos, using the observed luminosity function and ...

The Stellar Mass Components of Galaxies: Comparing Semi-Analytical Models with Observation [PDF]
Astrophys.J.712:734-745,2010, 2010 We compare the stellar masses of central and satellite galaxies predicted by three independent semianalytical models with observational results obtained from a large galaxy group catalogue constructed from the Sloan Digital Sky Survey.

The Effect of the Remnant Mass in Estimating Stellar Mass of Galaxies [PDF]
Publications of the Astronomical Society of Japan, 2013 The definition of the galactic stellar mass estimated from the spectral energy distribution is ambiguous in the literature; whether the stellar mass includes the mass of the stellar remnants, i.e. white dwarfs, neutron stars, and black holes, is not well described. The remnant mass fraction in the total (living+remnant) stellar mass of a simple stellar

Constraining the Stellar Mass Function in the Galactic Center via Mass Loss from Stellar Collisions [PDF]
Advances in Astronomy, 2010 The dense concentration of stars and high velocity dispersions in the Galactic centre imply that stellar collisions frequently occur. Stellar collisions could therefore result in significant mass loss rates. We calculate the amount of stellar mass lost due to indirect and direct stellar collisions and find its dependence on the present-day mass ...

Evolution of Mass Functions of Coeval Stars through Wind Mass Loss and Binary Interactions [PDF]
, 2015 Accurate determinations of stellar mass functions and ages of stellar populations are crucial to much of astrophysics. We analyse the evolution of stellar mass functions of coeval main sequence stars including all relevant aspects of single- and binary ...

The COSMOS2015 galaxy stellar mass function [PDF]
Astronomy & Astrophysics, 2017 We measure the stellar mass function (SMF) and stellar mass density of galaxies in the COSMOS field up to z ~ 6. We select them in the near-IR bands of the COSMOS2015 catalogue, which includes ultra-deep photometry from UltraVISTA-DR2, SPLASH, and Subaru/Hyper Suprime-Cam. At z> 2.5 we use new precise photometric redshifts with error σz = 0.03(1 + z)
