Scaling Relations of Early-Type Galaxies in MOND

Galaxies
We investigate the shape and morphology of early-type galaxies (ETGs) within the framework of Modified Newtonian Dynamics (MOND). Building on our previous studies, which demonstrated that the monolithic collapse of primordial gas clouds in MOND produces ...

The Baryonic Halos of Isolated Elliptical Galaxies

Galaxies, 2017
Without the interference of a number of events, galaxies may suffer in crowded environments (e.g., stripping, harassment, strangulation); isolated elliptical galaxies provide a control sample for the study of galaxy formation.

The Stellar Halos of Massive Elliptical Galaxies

, 2012
We use the Mitchell Spectrograph (formerly VIRUS-P) on the McDonald Observatory 2.7m Harlan J. Smith Telescope to search for the chemical signatures of massive elliptical galaxy assembly. The Mitchell Spectrograph is an integral-field spectrograph with a

Relativistic jets in narrow-line Seyfert 1 galaxies. New discoveries and open questions

EPJ Web of Conferences, 2013
Before the launch of the Fermi satellite only two classes of AGNs were known to produce relativistic jets and thus emit up to the γ-ray energy range: blazars and radio galaxies, both hosted in giant elliptical galaxies.

X-ray Binaries and Globular Clusters in Elliptical Galaxies

, 2002
The X-ray emission from normal elliptical galaxies has two major components: soft emission from diffuse gas and harder emission from populations of accreting (low-mass) stellar X-ray binaries (LMXB).

Hot gusts from elliptical galaxies

The Astrophysical Journal, 1981
The pulsed wind is an intrinsic mechanism for removing gas from elliptical galaxies and is based upon the suggestion that Type I supernovae originate in a young stellar population. In this model, a period of gas accumulation is followed by cooling and star formation which is followed by a burst of supernova activity and a short-lived but intense wind ...
