A Preferential Growth Channel for Supermassive Black Holes in Elliptical Galaxies at z ≲ 2

open access: yesThe Astrophysical Journal, 2023
The assembly of stellar and supermassive black hole (SMBH) mass in elliptical galaxies since z ∼ 1 can help to diagnose the origins of locally observed correlations between SMBH mass and stellar mass.

Mass Dependence of Galaxy–Halo Alignment in LOWZ and CMASS

open access: yesThe Astrophysical Journal, 2023
We measure the galaxy-ellipticity (GI) correlations for the Sloan Digital Sky Survey Data Release 12 LOWZ and CMASS samples with the shape measurements from the DESI Legacy Imaging Surveys.

Hot interstellar matter in elliptical galaxies [PDF]

open access: yes, 2009
Based on a number of new discoveries resulting from 10 years of Chandra and XMM-Newton observations and corresponding theoretical works, this is the first book to address significant progress in the research of the Hot Interstellar Matter in Elliptical ...

Clustercentric Distance or Local Density? It Depends on Galaxy Morphology

open access: yesThe Astrophysical Journal, 2023
Determining which between projected local density and distance from the cluster center plays a major role in regulating morphological fractions in clusters is a longstanding debate.

The ‘Photometric Plane’ of elliptical galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2002
The Sersic r^(1/n) index n of an elliptical galaxy (or bulge) has recently been shown to correlate strongly (r=0.8) with a galaxy's central velocity dispersion. This index could therefore prove extremely useful and cost-effective (in terms of both telescope time and data reduction) for many fields of extragalactic research.

Tracing Galaxy Evolution by Their Present-Day Luminosity Function

open access: yesOpen Astronomy, 2011
Galaxy luminosity functions are derived for different morphological types and various colors of galaxies, to trace the evolutionary effects which a priori should be different for void and supercluster galaxies.

Fundamental Plane of Elliptical Galaxies in f(R) Gravity: The Role of Luminosity

open access: yesAtoms, 2018
The global properties of elliptical galaxies are connected through the so-called fundamental plane of ellipticals, which is an empirical relation between their parameters: effective radius, central velocity dispersion and mean surface brightness within ...

Slowly Rotating Accretion Flow Around Supermassive Black Holes in Elliptical Galaxies: Case With Outflow

open access: yesThe Astrophysical Journal, 2023
Observational evidence and many numerical simulations show the existence of winds (i.e., uncollimated outflows) in the accretion systems of elliptical galaxy centers.

Triaxial Orbit-based Dynamical Modeling of Galaxies with Supermassive Black Holes and an Application to Massive Elliptical Galaxy NGC 1453

open access: yesThe Astrophysical Journal, 2022
Most stellar-dynamical determinations of the masses of nearby supermassive black holes (SMBHs) have been obtained with the orbit superposition technique under the assumption of axisymmetry.
