Recent changes in a flickering variability of the black hole X-ray transient V616 Mon = A0620-00
V616 Mon = A0620-00 is a prototype of black hole transient X-ray binaries. Our 2003-16 optical photometry of the object during X-ray quiescence, obtained by 50-250 cm telescopes in Crimea, Caucasus
Structure of the Periphery of the Large Magellanic Cloud Revealed by 2MASS
In order to understand the equilibrium structure of the Large Magellanic Cloud (LMC), I have reexamined the content of the 2MASS database on its periphery. Based on the dereddened colors of the LMC’s
The Sunyaev-Zel'dovich effect in WMAP data
Using WMAP 5 year data, we look for the average Sunyaev-Zel'dovich effect (SZE) signal from clusters of galaxies by stacking the regions around hundreds of known X-ray clusters. We detect the average
An asymmetry index is derived from ellipse fitting to galaxy images that gives weight to faint outer features and is not strongly redshift dependent. These measures are made on a sample of 13 Two
Constraints on Type Ib/c and GRB Progenitors
Although there is strong support for the collapsar engine as the power source of long-duration gamma-ray bursts (GRBs), we still do not definitively know the progenitor of these explosions. Here we
The Cosmic Infrared Background Resolved by Spitzer. Contributions of Mid-Infrared Galaxies to the Far-Infrared Background.
Aims. We quantify the contributions of 24 mu m galaxies to the Far-Infrared ( FIR) Background at 70 and 160 mu m. We provide new estimates of the Cosmic Infrared Background ( CIB), and compare it
Observational Gamma-ray Cosmology
We discuss how measurements of the absorption of gamma‐rays from GeV to TeV energies via pair production on the extragalactic background light (EBL) can probe important issues in galaxy formation.
The all-sky distribution of 511 keV electron-positron annihilation emission
We present a map of 511 keV electron-positron annihilation emission, based on data accumulated with the SPI spectrometer aboard ESA's INTEGRAL gamma-ray observatory, that covers approximately 95% of
Distant FR I radio galaxies in the Hubble Deep Field: implications for the cosmological evolution of radio-loud AGN
Deep and high-resolution radio observations of the Hubble Deep Field and flanking fields have shown the presence of two distant edge-darkened FR I radio galaxies, allowing for the first time an
Powerful jets from black hole X-ray binaries in low/hard X-ray states
Four persistent (Cygnus X-1, GX 339−4, GRS 1758−258 and 1E 1740.7−2942) and three transient (GS 2023+38, GRO J0422+32 and GS 1354−64) black hole X-ray binary systems have been extensively observed at
