Introducing the NEWHORIZON simulation: Galaxy properties with resolved internal dynamics across cosmic time [PDF]
Astronomy & Astrophysics, 2020 Hydrodynamical cosmological simulations are increasing their level of realism by considering more physical processes and having greater resolution or larger statistics.

First cosmology results using type Ia supernovae from the Dark Energy Survey: the effect of host galaxy properties on supernova luminosity [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We present improved photometric measurements for the host galaxies of 206 spectroscopically confirmed type Ia supernovae discovered by the Dark Energy Survey Supernova Program (DES-SN) and used in the first DES-SN cosmological analysis.

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. We have compiled a sample of galaxies in 46 large nearby voids that were identified using the Sloan Digital Sky Survey DR4, which provides ...

How Do Galaxy Properties Affect Void Statistics? [PDF]
Astrophysical Journal, 2020 Using mapping from dark matter halos to galaxy properties based on hydrodynamical simulations, we explore the impact of galaxy properties on the void size function and the void–galaxy correlation function.

Galaxy properties in the cosmic web of EAGLE simulation [PDF]
, 2020 We investigate the dependence of the galaxy properties on cosmic web environments using the most up-to-date hydrodynamic simulation: Evolution and Assembly of Galaxies and their Environments (EAGLE).

The relationship between black hole mass and galaxy properties: examining the black hole feedback model in IllustrisTNG [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Supermassive black hole feedback is thought to be responsible for the lack of star formation, or quiescence, in a significant fraction of galaxies. We explore how observable correlations between the specific star formation rate (sSFR), stellar mass ...

Photometric Properties of Clusters of Galaxies [PDF]
The Astrophysical Journal Supplement Series, 1996 We report the first results of a long term program aimed at investigating the photometric properties of the cores of Abell and X-ray selected (EMSS, \cite{emss}) clusters of galaxies. We observed 77 clusters of galaxies in the redshift range $0.05\leq z \leq 0.25$ in the Gunn $g$, $r$ and $i$ filters: in this paper we present the data on 59 clusters ...

The Host-galaxy Properties of Type 1 versus Type 2 Active Galactic Nuclei [PDF]
Astrophysical Journal, 2019 The unified model of active galactic nuclei (AGNs) proposes that different AGN optical spectral types are caused by different viewing angles with respect to an obscuring “torus.” Therefore, this model predicts that type 1 and type 2 AGNs should have ...

Some Properties of Galaxy Structures [PDF]
Open Astronomy, 2011 Abstract 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). At first, we analyzed the orientation of galaxies in the 247 optically selected rich Abell clusters, having at least 100 members. The distribution of the position angles
