Galaxy Quenching with Mass Growth History of Galaxy Groups and Clusters: The Importance of Post-processing

open access: yesThe Astrophysical Journal, 2023
We investigate the fraction of quenched satellite galaxies in host galaxy groups and clusters using TNG300 in the IllustrisTNG cosmological magnetohydrodynamical simulations.

The Environmental Dependence of the Evolving S0 Fraction [PDF]

open access: yes, 2010
We reinvestigate the dramatic rise in the S0 fraction, f_S0, within clusters since z ~ 0.5. In particular, we focus on the role of the global galaxy environment on f_S0 by compiling, either from our own observations or the literature, robust line-of ...

Dark matter halo properties of GAMA galaxy groups from 100 square degrees of KiDS weak lensing data [PDF]

open access: yes, 2015
The Kilo-Degree Survey is an optical wide-field survey designed to map the matter distribution in the Universe using weak gravitational lensing.

Using member galaxy luminosities as halo mass proxies of galaxy groups

open access: yes, 2015
Reliable halo mass estimation for a given galaxy system plays an important role both in cosmology and galaxy formation studies. Here we set out to find the way that can improve the halo mass estimation for those galaxy systems with limited brightest ...

GALAXY GROUPS: A 2MASS CATALOG [PDF]

open access: yes, 2015
A galaxy group catalog is built from the sample of the 2MASS Redshift Survey almost complete to Ks = 11.75 over 91% of the sky. Constraints in the construction of the groups were provided by scaling relations determined by close examination of well ...

Observational Evidence for an Age Dependence of Halo Bias

open access: yes, 2006
We study the dependence of the cross-correlation between galaxies and galaxy groups on group properties. Confirming previous results, we find that the correlation strength is stronger for more massive groups, in good agreement with the expected mass ...

GALAXY GROUPS IN THE 2MASS REDSHIFT SURVEY [PDF]

open access: yes, 2016
A galaxy group catalog is constructed from the 2MASS Redshift Survey (2MRS) with the use of a halo-based group finder. The halo mass associated with a group is estimated using a “GAP” method based on the luminosity of the central galaxy and its gap with ...

Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

open access: yesAdvanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

Luminosity and Stellar Mass Functions of Faint Photometric Satellites around Spectroscopic Central Galaxies from DESI Year-1 Bright Galaxy Survey

open access: yesThe Astrophysical Journal
We measure the luminosity functions (LFs) and stellar mass functions (SMFs) of photometric satellite galaxies around spectroscopically identified isolated central galaxies (ICGs). The photometric satellites are from the DESI Legacy Imaging Surveys (DR9),

The matter distribution in the local universe as derived from galaxy groups in SDSS DR12 and 2MRS [PDF]

open access: yes, 2015
Context. Friends-of-friends algorithms are a common tool to detect galaxy groups and clusters in large survey data. In order to be as precise as possible, they have to be carefully calibrated using mock catalogues. Aims. We create an accurate and robust
