The spectrum is not consistent with the existence of a hard X-ray tail at the flux level reported by Bazzano el al.

The Fe K-beta line blend is also weakly detected. The Fe K-alpha line blend is strongly detected, from which we infer 0.18-0.36 solar abundance in the X-ray emitting gas.

Using the best-fitting parameters, the gas is found to be a significant fraction (25 percent) of the total cluster mass. This analysis reduces the total cluster mass by a factor of 3-5 below the optically derived virial mass. To model the spectrum more accurately, we have performed fits of polytropic models and find that the gas is well fitted by an equation of state with polytropic index ranging between 1.38 and 1.6. The spectrum is not well fitted by an isothermal bremsstrahlung model with an Fe line. Abilities are scored from three to 15 in the Glasgow Coma Scale. The coherence of speech also provides important clues. While the fraction of nuclear activity in Coma infall and CG galaxies is similar, which may reflect the influence of multi-galaxy gravitational interactions, the X-ray emission from individual galaxies in the two environments is also markedly different.The HEAO 1 A-2 and OSO 8 observations of the Coma Cluster of galaxies in the 2-60 keV energy band are presented. This 15-point test helps a doctor or other emergency medical personnel assess the initial severity of a brain injury by checking a person's ability to follow directions and move their eyes and limbs. From our observations of the diffuse X-ray emission in CGs, we find it unlikely that the intragroup hot gas is responsible for the rapid transformation of galaxies from star-forming to quiescent. We also used our multi-wavelength observations to identify active galaxies in the Coma infall sample and find that the fraction of active galaxies is similar to the CG environment. Formerly called AXAF, Chandra was launched on July 23, 1999, and is the largest and most sophisticated X-ray observatory to date. The Coma galaxies agree with the scaling relations between LX, SFR, and stellar mass from the literature within uncertainties, while the CG members often show an X-ray excess. We also investigate the relations between LX, SFR, and stellar mass from individual members of CGs and the infall region of the nearby Coma galaxy cluster, which is the only environment that has a mid-infrared galaxy color distribution similar to CGs. It is high-mass CGs that also agree well with the observed scaling relations between diffuse X-ray luminosity (LX), gas temperature, and velocity dispersion predicted and observed in galaxy clusters, indicating that the hot gas in only massive CGs is virialized. The galaxy-linked hot gas is coupled with high star formation rates (SFRs), while only CGs with high baryonic masses have substantial hot gas linked to the group environment.

From a sample of 19 CGs, we find the morphology of hot gas in low-mass groups is varied, and most systems have hot gas (if any) associated with only individual members. X Ray Business Plan: Level: University, College, High School, Masters, PHD, Undergraduate. First, we study the distribution and properties of the intragroup diffuse X-ray emission in compact groups (CGs) of galaxies. We use X-ray observations from XMM- Newton and the Chandra X-ray Observatory, and multi-wavelength ancillary data, to investigate the X-ray emission of galaxies. In this thesis, we have explored what information may be gleaned from X-ray observations of galaxies in dense environments.
