Carinae Majoris II

Greetings to anyone who may come across this site. However, this site is now over a year old (as of 24.07.2011). This is also my old blogging site, and since November 2010 it has been replaced with:

A Radio Transient In M82: An SS433 Analogue?

Lying at a distance of 3.6Mpc (Freedman et al. 1994), M82 is observed to be one of the most tumultuous galaxies in the local group, with rapid periods of both star formation and evolution: a designated starburst galaxy (Kronberg et al. 1985; Rieke et al. 1993; Pedlar & Muxlow 1995). In addition to this intense star formation, radio observations have revealed approximately 60 compact radio sources in the central region of M82 (McDonald et al. 2002). A quarter of these sources are of unknown origin. As well as hosting a variety of compact sources, continual radio surveys have also found various transient sources of an undetermined nature (e.g Kronberg & Sramek 1985; Muxlow et al. 1994).

M33 X-7: Evolution Of An Unusual Black Hole Binary System

In a distant galaxy hidden away in one of the furthest corners of our Universe, lives an extraordinarily massive black hole orbiting around its sister binary star in a highly unusual tight orbit: named M33 X-7. M33 X-7 has been observed as one of the most interesting astrophysical objects discovered, with a multitude of unusual properties: the tight orbit, the large masses of the star and black hole, the X-ray luminosity of the black hole and why its companion star is less luminous than one would expect, given its mass. This provides a gap, a gap for a model which explains all of these observations (Abubekerov et al. 2009). Read more
