America's First Black Town: Brooklyn, Illinois, 1830-1915

The Faint “heartbeats” of Igr J17091–3624: an Exceptional Black-hole Candidate

We report on the first 180 days of RXTE observations of the outburst of the black hole candidate IGR J17091–3624. This source exhibits a broad variety of complex light curve patterns including periods of strong flares alternating with quiet intervals. Similar patterns in the X-ray light curves have been seen in the (up to now) unique black hole system GRS 1915+105. In the context of the variabi...

Third-Party Appeal Rights: Past and Future

The first comprehensive town planning legislation in Australia was enacted by the Western Australian Parliament in 1929. This followed a number of events in Australia to showcase the benefits of town planning, from 1914, onwards. They included an Australasian town planning tour by Charles Reade on behalf of the Garden Cities and Town Planning Association of Great Britain, in 1914 -1915, after w...

GRS 1915 + 105 : The brightest Galactic black hole

We compare the evolution of spectral shape with luminosity in GRS 1915+105 with that of ‘normal’ black holes. The pathological time variability of GRS 1915+105 does not indicate that it belongs in a different class to all the other objects. At comparable fraction of Eddington luminosity its spectra and (more importantly) time variability behaviour are similar to that seen in the ‘normal’ black ...

Inner disk oscillations

The RXTE observations of GRS 1915+105 have given a new impulse to the study of spectral and timing properties of the X-ray emission of black hole candidates. At variance with any other known source, GRS 1915+105 shows dramatic changes on time scales as short as a tenth of a second. These changes are associated to marked spectral changes which have been interpreted as changes of the observable i...
