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…
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…
AGN Feedback in groups and clusters of galaxies
S. Raychaudhury, S. Giacintucci, E. O'Sullivan +5
The lack of very cool gas at the cores of groups and clusters of galaxies, even where the cooling time is significantly shorter than the Hubble time, has been interpreted as eviden…
A Joint GMRT/X-ray study of galaxy groups
E. O'Sullivan, S. Giacintucci, J. M. Vrtilek +4
We present results from combined low-frequency radio and X-ray studies of nearby galaxy groups. We consider two main areas: firstly, the evolutionary process from spiral-dominated,…
Luminosity functions of LMXBs in Centaurus A: globular clusters versus the field
R. Voss, M. Gilfanov, G. R. Sivakoff +16
We study the X-ray luminosity function (XLF) of low mass X-ray binaries (LMXB) in the nearby early-type galaxy Centaurus A, concentrating primarily on two aspects of binary populat…
High-energy particle acceleration at the radio-lobe shock of Centaurus A
J. H. Croston, R. P. Kraft, M. J. Hardcastle +19
We present new results on the shock around the southwest radio lobe of Centaurus A using data from the Chandra Very Large Programme observations. The X-ray spectrum of the emission…
