Cavities and shocks in the galaxy group HCG 62 as revealed by Chandra, XMM and GMRT data
Myriam Gitti, Ewan O'Sullivan, Simona Giacintucci +4
We report on the results of an analysis of Chandra, XMM-Newton and new GMRT data of the X-ray bright compact group of galaxies HCG 62, which is one of the few groups known to posse…
Long Term Monitoring of the Dynamics and Particle Acceleration of Knots in the Jet of Centaurus A
J. L. Goodger, M. J. Hardcastle, J. H. Croston +16
We present new and archival multi-frequency radio and X-ray data for Centaurus A obtained over almost 20 years at the VLA and with Chandra, with which we measure the X-ray and radi…
Comparing X-ray and Dynamical Mass Profiles in the Early-Type Galaxy NGC 4636
Ria Johnson, Dalia Chakrabarty, Ewan O'Sullivan +1
We present the results of an X-ray mass analysis of the early-type galaxy NGC 4636, using Chandra data. We have compared the X-ray mass density profile with that derived from a dyn…
Topographic Mapping of astronomical light curves via a physically inspired Probabilistic model
Nikolaos Gianniotis, Peter Tino, Steve Spreckley +1
We present a probabilistic generative approach for constructing topographic maps of light curves from eclipsing binary stars. The model defines a low-dimensional manifold of local…
Fossil Galaxy Groups -- Ideal Laboratories for Studying the Effects of AGN Heating
Nazirah N. Jetha, Habib Khosroshahi, Somak Raychaudhury +2
We present the first of a sample of fossil galaxy groups with pre-existing Chandra and/or XMM-Newton X-ray observations and new or forthcoming low frequency GMRT data -- RXJ1416.4+…
Uncovering delayed patterns in noisy and irregularly sampled time series: an astronomy application
Juan C. Cuevas-Tello, Peter Tino, Somak Raychaudhury +2
We study the problem of estimating the time delay between two signals representing delayed, irregularly sampled and noisy versions of the same underlying pattern. We propose and de…
