Emission from the Prototypical LINER Galaxy NGC 1052
We examine the 0.1 to 10.0 keV X-ray spectrum of the bright nuclear LINER galaxy NGC 1052, one of two elliptical galaxies known to contain a luminous H2O maser. The observed 2.0 − 10.0 keV spectrum is unusually flat (photon index Γ ∼ 0.2) and best described as intrinsically power-law shaped nuclear flux that is either (1) attenuated by a complex absorber with ∼ 70% of the nuclear flux absorbed ...

متن کاملEvolutionary History of the Elliptical Galaxy NGC 1052
We have obtained Keck spectra for 16 globular clusters (GCs) associated with the merger remnant elliptical NGC 1052, as well as a long-slit spectrum of the galaxy. We derive ages, metallicities and abundance ratios from simple stellar population models using the methods of Proctor & Sansom (2002), applied to extragalactic GCs for the first time. A number of GCs indicate the presence of strong b...
متن کاملDark matter density profiles from the Jeans equation
We make a simple analytical study of radial profiles of dark matter structures, with special attention to the question of the central radial density profile. We let our theoretical assumptions be guided by results from numerical simulations, and show that at any radius where both the radial density profile, ρ, and the phase-space-like density profile, ρ/σǫ, are exact power laws, the only allowe...
متن کاملDense Plasma Torus in the GPS Galaxy NGC 1052
We report results from nearly simultaneous pentachromatic VLBI observations towards a nearby GPS galaxy NGC 1052. The observations at 1.6 and 4.8 GHz with VSOP, and at 2.3, 8.4, and 15.4 GHz with VLBA, provide linear resolutions of ∼ 0.1 pc. Convex spectra of a double-sided jet imply that synchrotron emission is obscured through foreground cold dense plasma, in terms of free–free absorption (FF...
