X-Ray Probes of Cosmic Star-Formation History
Pranab Ghosh, Nicholas E. White
We discuss the imprints left by a cosmological evolution of the star formation rate (SFR) on the evolution of X-ray luminosities Lx of normal galaxies, using the scheme proposed by…
Low-Mass X-Ray Binaries, Millisecond Radio Pulsars, and the Cosmic Star Formation Rate
Nicholas E. White, Pranab Ghosh
We report on the implications of the peak in the cosmic star-formation rate (SFR) at redshift z ~ 1.5 for the resulting population of low-mass X-ray binaries(LMXB) and for that of…
X-ray Polarization from Black Holes: GEMS Scientific White Paper
Jeremy Schnittman, Lorella Angelini, Matthew Baring +27
We present here a summary of the scientific goals behind the Gravity and Extreme Magnetism SMEX (GEMS) X-ray polarimetry mission's black hole (BH) observing program. The primary ta…
Young pre-Low-Mass X-ray Binaries in propeller phase : Nature of the 6.7-hour periodic X-ray source 1E 161348-5055 in RCW 103
Harshal Bhadkamkar, Pranab Ghosh
Discovery of the 6.7-hour periodicity in the X-ray source 1E 161348-5055 in RCW 103 has led to investigations of the nature of this periodicity. We explore a model for 1E 161348-50…
Collective Properties of X-ray Binary Populations of Galaxies III. The Low-mass X-ray Binary Luminosity Function
Harshal Bhadkamkar, Pranab Ghosh
Continuing our exploration of the collective properties of low-mass X-ray binaries (LMXBs) in the stellar fields of normal galaxies, we compute in this paper the expected X-ray lum…
White Paper on GEMS Study of Polarized X-rays from Neutron Stars
Pranab Ghosh, Lorella Angelini, Matthew Baring +27
We examine the expected X-ray polarization properties of neutron-star X-ray sources of various types, e.g., accretion and rotation powered pulsars, magnetars, and low-mass X-ray bi…
