Temperature Profiles of Hot Gas In Early Type Galaxies
Dong-Woo Kim, Liam Traynor, Alessandro Paggi +12
Using the data products of the Chandra Galaxy Atlas (Kim et al. 2019a), we have investigated the radial profiles of the hot gas temperature in 60 early type galaxies. Considering t…
Two years of non-thermal emission from the binary neutron star merger GW170817: rapid fading of the jet afterglow and first constraints on the kilonova fastest ejecta
A. Hajela, R. Margutti, K. D. Alexander +27
We present Chandra and VLA observations of GW170817 at ~521-743 days post merger, and a homogeneous analysis of the entire Chandra data set. We find that the late-time non-thermal…
Optical characterization of WISE selected blazar candidates
Raniere de Menezes, Harold A. Peña-Herazo, Ezequiel J. Marchesini +8
Over the last decade more than five thousand gamma-ray sources were detected by the Large Area Telescope (LAT) on board Fermi Gamma-ray Space Telescope. Given the positional uncert…
COMP2CAT: hunting compact double radio sources in the local Universe
Ana Jimenez-Gallardo, Francesco Massaro, Alessandro Capetti +7
We present a catalog of compact double radio galaxies (hereafter COMP2) listing 43 edge-brightened radio sources whose projected linear size does not exceed 60 kpc, the typica…
X-ray Photons in the CO 2-1 'Lacuna' of NGC 2110
G. Fabbiano, A. Paggi, M. Elvis
A recent ALMA study of the Seyfert 2 Active Galactic Nucleus (AGN) NGC 2110 by Rosario et al. (2019) has reported a remarkable lack of CO 2-1 emission from the circumnuclear region…
WATCAT: a tale of wide-angle tailed radio galaxies
V. Missaglia, F. Massaro, A. Capetti +4
We present a catalog of 47 wide-angle tailed radio galaxies (WATs), the WATCAT; these galaxies were selected by combining observations from the National Radio Astronomy Observatory…
