Mass Dependence of Galaxy–Halo Alignment in LOWZ and CMASS
The 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.

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

The Manifold of Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1987 Global properties of elliptical galaxies, such as the luminosity, radius, projected velocity dispersion, projected luminosity density, etc., form a two-dimensional family. This “fundamental plane” of elliptical galaxies can be defined by the velocity dispersion and mean surface brightness, and its thickness is presently given by the measurement error ...

The Manifold of Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1983 The significant number of dimensions of the manifold is two. Notwithstanding the contamination of the second dimension by projection effects, there are arguments for an intrinsic variation.

On the Formation of Elliptical Galaxies [PDF]
The Astrophysical Journal, 1975 Simple collapse and violent relaxation models produce sharply cut off envelopes with ϱ(r) ∝ r–4, whereas actual elliptical galaxies have more extended envelopes approximately given by ϱ(r) ∝ r–3 as implied by Hubble's Law. Numerical models are presented, showing that when cosmological infall effects are included, galaxies are produced with more ...

Elliptical galaxies: Rotationally distorted, after all [PDF]
Serbian Astronomical Journal, 2009 On the basis of earlier investigations on homeoidally striated Mac Laurin spheroids and Jacobi ellipsoids (Caimmi and Marmo 2005, Caimmi 2006a, 2007), different sequences of configurations are defined and represented in the ellipticity-rotation plane ...

Tracing Galaxy Evolution by Their Present-Day Luminosity Function
Open 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.

Clustercentric Distance or Local Density? It Depends on Galaxy Morphology
The 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.
