Unifying the observational diversity of isolated neutron stars via magneto-thermal evolution models.
Observations of magnetars and some of the high magnetic field pulsars have shown that their thermal luminosity is systematically higher than that of classical radiopulsars, thus confirming the idea
Neutrino Trapping and Accretion Models for Gamma-Ray Bursts
Many models of gamma-ray bursts (GRBs) invoke a central engine consisting of a black hole of a few solar masses accreting matter from a disk at a rate of a fraction to a few solar masses per second.
A study of compact object mergers as short gamma-ray burst progenitors
We present a theoretical study of double compact objects as potential short/hard gamma-ray burst (GRB) progenitors. An updated population synthesis code, StarTrack, is used to calculate properties of
Magnetic Drag on Hot Jupiter Atmospheric Winds
Hot Jupiters, with atmospheric temperatures T 1000 K, have residual thermal ionization levels sufficient for the interaction of ions with the planetary magnetic field to result in a sizable magnetic
A new low magnetic field magnetar: the 2011 outburst of Swift J1822.3–1606
We report on the long-term X-ray monitoring withSwift,RXTE,Suzaku,Chandra, andXMM-Newton of the outburst of the newly discovered magnetar Swift J1822.3−1606 (SGR 1822−1606), from the first
Radio Foregrounds for the 21 Centimeter Tomography of the Neutral Intergalactic Medium at High Redshifts
Absorption or emission against the cosmic microwave background (CMB) radiation may be observed in the redshifted 21 cm line if the spin temperature of the neutral intergalactic medium (IGM) prior to
Off-axis prompt X-ray transients from the cocoon of short gamma-ray bursts
We present the results of numerical simulations of the prompt emission of short-duration gamma-ray bursts. We consider emission from the relativistic jet, the mildly relativistic cocoon, and the
Bondi Accretion and the Problem of the Missing Isolated Neutron Stars
A large number of neutron stars (NSs), ~109, populate the Galaxy, but only a tiny fraction of them is observable during the short radio pulsar lifetime. The majority of these isolated NSs, too cold
The Post-Burst Awakening of the Anomalous X-Ray Pulsar in Westerlund 1
On 2006 September 21, an intense (~1039 erg s-1) and short (20 ms) burst was detected by Swift BAT at a position consistent with that of the candidate anomalous X-ray pulsar (AXP) CXOU
The first outburst of the new magnetar candidate SGR 0501+4516
We report here on the outburst onset and evolution of the new soft gamma-ray repeater SGR 0501+4516. We monitored the new SGR with XMM- Newton starting on 2008 August 23, 1 day after the source
