The core fundamental plane of B2 radio galaxies

, 2009
The photometric, structural and kinematical properties of the centers of elliptical galaxies, harbor important information of the formation history of the galaxies.

The Way We Measure: Comparison of Methods to Derive Radial Surface Brightness Profiles [PDF]

, 2016
The breaks and truncations in the luminosity profile of face-on spiral galaxies offer valuable insights in their formation history. The traditional method of deriving the surface photometry profile for face-on galaxies is to use elliptical averaging.

Dwarf elliptical galaxies

The Astrophysical Journal, 1983
We propose that dwarf elliptical galaxies are the bound remnants of more massive stellar systems, such as a parent galaxy which has lost more than half its mass in gas ejection during a burst of star formation, or an unbound tidal debris produced during the interaction of two giant galaxies.

Searching for tidal tails - investigating galaxy harassment

, 2005
Galaxy harassment has been proposed as a physical process that morphologically transforms low surface density disc galaxies into dwarf elliptical galaxies in clusters.

Quantifying the Impact of Relativistic Precession on Tidal Disruption Event Light Curves

Astronomische Nachrichten, EarlyView.
ABSTRACT The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impact of precession on the light curves of tidal disruption events (TDE).

The Abundance Pattern of O, Ne, Mg, and Fe in the Interstellar Medium of S0 Galaxy NGC 4382 Observed with Suzaku [PDF]

, 2009
We derived O, Ne, and Mg abundances in the interstellar medium (ISM) of a relatively isolated S0 galaxy, NGC 4382, observed with the Suzaku XIS instruments and compared the O/Ne/Mg/Fe abundance pattern to those of the ISM in elliptical galaxies.

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

Astronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

Dynamics of Elliptical Galaxies with Planetary Nebulae in Modified Newtonian Dynamics

, 2016
The dynamics of an elliptical galaxy within a couple of effective radii can be probed effectively by stars. However, at larger distances planetary nebulae (PNe) replace stars as the tracer of the dynamics.

Evolution of the Color-Magnitude Relation in Galaxy Clusters at z ~1 from the ACS Intermediate Redshift Cluster Survey [PDF]

, 2008
We apply detailed observations of the Color-Magnitude Relation (CMR) with the ACS/HST to study galaxy evolution in eight clusters at z~1. The early-type red sequence is well defined and elliptical and lenticular galaxies lie on similar CMRs.
