A search for X-ray flashes with XMM-Newton

Law, Nicholas M.; Kulkarni, Shrinivas R.; Rutledge, Robert E.

We searched for X-ray flashes (XRFs) - which we defined as ~10-s duration transient X-ray events observable in the 0.4-15 keV passband - in fields observed using XMM-Newton with the EPIC/pn detector. While we find two non-Poissonian events, the astrophysical nature of the events is not confirmed in fully simultaneous observations with the EPIC/MOS…

Properties of serendipitous X-ray flares discovered in XMM-Newton observations

Ramsay, Gavin; Trenholme, Duncan; Foley, Carl

We present the results of a search of the XMM-Newton public data archive for stellar X-ray flares. We find eight flaring sources for which we identify seven optical counterparts. Three of these sources have distance estimates which allow us to determine their luminosities. Based on the decay time of the flares and their luminosity, we derive loop …

The XMM-Newton/2dF survey - V. The radio properties of the X-ray population

Georgakakis, A.; Georgantopoulos, I.; Akylas, A. +3 more

In this paper, we cross-correlate the FIRST (Faint Images of the Radio Sky at Twenty centimeters) 1.4-GHz radio survey with a wide-field (1.6 deg²) shallow [f_X(0.5 - 8keV) ~ 10^-14erg s^-1]XMM-Newton survey. We find 12 X-ray/radio matches representing 4 per cent of the X-ray-selected sample. Most of them a…
