A Fundamental Plane Relation for the X-ray Gas in Normal Elliptical Galaxies
We report on the discovery of a new correlation between global parameters of the hot interstellar gas in elliptical galaxies. We reanalyze archival Chandra data for 30 normal early-type systems, removing the contributions of resolved and unresolved point sources to reveal the X-ray morphology of the hot gas. We determine the half-light radius, RX , and the mean surface brightness, IX , from the...
متن کاملThe Fundamental Plane of Cluster Elliptical Galaxies
Using deep Hubble Space Telescope Advanced Camera for Surveys imaging and Very Large Telescope FOcal Reducer/low dispersion Spectrograph 2 spectra, we determined the velocity dispersions, effective radii, and surface brightnesses for four early-type galaxies in the cluster RDCS 1252.9 2927. All four galaxies are massive, z p 1.237 greater than . These four galaxies, combined with three from RDC...
متن کاملSimulating the Hot X-ray Emitting Gas in Elliptical Galaxies
We study the chemo-dynamical evolution of elliptical galaxies and their hot X-ray emitting gas using high-resolution cosmological simulations. Our Tree N-body/SPH code includes a self-consistent treatment of radiative cooling, star formation, supernovae feedback, and chemical enrichment. We present a series of ΛCDM cosmological simulations which trace the spatial and temporal evolution of heavy...
متن کاملThe neutral gas content of X-ray bright elliptical galaxies
Sensitive CO observations are presented for a sample of elliptical galaxies which are luminous X-ray and weak far infrared (FIR) emitters. Only non-detections were obtained. The absence of detectable amounts of CO (this includes the previously ‘detected’ prototypical galaxy NGC4472) does not support those standard cooling flow scenarios in which dust grain sputtering reduces the FIR luminosity,...
متن کاملNear-Infrared Fundamental Plane of Elliptical Galaxies
Near-infrared (2.2 μm) observations of a sample of 48 elliptical galaxies in the Coma cluster have been carried out and used to study the near-ir fundamental plane (FP) of ellipticals in this cluster. An rms scatter of 0.072 dex was found for this relation, similar to that of its optical counterpart, using the same sample of galaxies. This corresponds to an uncertainty of 18% in distances to in...
