Relativistic inflow in the Seyfert 1 Mrk 335 revealed through X-ray absorption
A. L. Longinotti, S. Sim, K. Nandra +2
The analysis of hard X-ray features in XMM-Newton data of the bright Sy 1 galaxy Mrk 335 is reported here. The presence of a broad, ionised iron K alpha emission line in the spectr…
A new definition of the intermediate group of gamma-ray bursts
I. Horvath, L. G. Balazs, Z. Bagoly +2
Gamma-ray bursts can be divided into three groups ("short", "intermediate", "long") with respect to their durations. This classification is somewhat imprecise, since the subgroup o…
A Galaxy Cluster Near NGC 720
H. Arp
The galaxy cluster RXJ 0152.7-1357 is emitting X-rays at the high rate of 148 counts . It would be one of the most luminous X-ray clusters known if it is at its redshift d…
Supernova outflows in galaxy formation
Cecilia Scannapieco, Patricia B. Tissera, Simon D. M. White +1
We investigate the generation of galactic outflows by supernova feedback in the context of SPH cosmological simulations. We use a modified version of the code GADGET-2 which includ…
Accretion of helium and metal-rich gas onto neutron stars and black holes at high luminosities
J. Dunkel, J. Chluba, R. A. Sunyaev
Ultraluminous X-ray sources fed by Wolf-Rayet star winds and X-ray bursters in ultracompact binaries with He or C white dwarfs have accretion disks, whose properties may significan…
Nearby star cluster formation: Probes of cosmological galaxy evolution
P. Anders, R. de Grijs, U. Fritze-v. Alvensleben
(abridged) The old Star Cluster (SC) systems surrounding any sofar investigated galaxy represent a powerful tool for the understanding of the cosmological evolution of their host g…
