The origin of hypervelocity white dwarfs in the merger-disruption of He-CO white dwarfs
Hila Glanz, Hagai B. Perets, Aakash Bhat +1
Hypervelocity white dwarfs (HVWDs) are stellar remnants moving at speeds exceeding the Milky Way's escape velocity. The origins of the fastest HVWDs are enigmatic, with proposed fo…
Measuring Black Hole Spins through X-ray Reflection Spectroscopy and the Relativistic Precession Model: the case of XTE J1859+226
Gitika Mall, Honghui Liu, Cosimo Bambi +2
The development of techniques to measure accurately black hole spins is crucial to study the physics and astrophysics of these objects. X-ray reflection spectroscopy is currently t…
Variability in high-mass X-ray binaries
F. Fuerst, P. Kretschmar, V. Grinberg +5
Strongly magnetized, accreting neutron stars show periodic and aperiodic variability over a wide range of time scales. By obtaining spectral and timing information on these differe…
Black hole lightning due to particle acceleration at subhorizon scales
MAGIC Collaboration, J. Aleksić, S. Ansoldi +151
Supermassive black holes with masses of millions to billions of solar masses are commonly found in the centers of galaxies. Astronomers seek to image jet formation using radio inte…
Unusual Flaring Activity in the Blazar PKS 1424-418 during 2008-2011
S. Buson, F. Longo, S. Larsson +24
Context. Blazars are a subset of active galactic nuclei (AGN) with jets that are oriented along our line of sight. Variability and spectral energy distribution (SED) studies are cr…
A Suzaku View of Cyclotron Line Sources and Candidates
K. Pottschmidt, S. Suchy, E. Rivers +20
Seventeen accreting neutron star pulsars, mostly high mass X-ray binaries with half of them Be-type transients, are known to exhibit Cyclotron Resonance Scattering Features (CRSFs)…
Fermi-LAT Observations of Markarian 421: the Missing Piece of its Spectral Energy Distribution
LAT collaboration, A. A. Abdo et al., the MAGIC collaboration +4
We report on the gamma-ray activity of the high-synchrotron-peaked BL Lacertae object Mrk 421 during the first 1.5 years of Fermi operation, from 2008 August 5 to 2010 March 12. We…
Suzaku observations of the HMXB 1A 1118-61
Slawomir Suchy, Katja Pottschmidt, Richard E. Rothschild +12
We present broad band analysis of the Be/X-ray transient 1A 1118-61 by Suzaku at the peak of its 3rd observed outburst in January 2009 and 2 weeks later when the source flux had de…
Insights Into the High-Energy Gamma-ray Emission of Markarian 501 from Extensive Multifrequency Observations in the Fermi Era
LAT collaboration, A. A. Abdo et al., the MAGIC collaboration +6
We report on the gamma-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average LAT gamma-ray spectrum of Mrk 501 can be well descr…
Search for a diffuse flux of high-energy with the ANTARES neutrino telescope
ANTARES Collaboration, J. A. Aguilar, I. Al Samarai +141
A search for a diffuse flux of astrophysical muon neutrinos, using data collected by the ANTARES neutrino telescope is presented. A sr sky was monitored for a tot…
Fermi Large Area Telescope View of the Core of the Radio Galaxy Centaurus A
Fermi Collaboration, A. Falcone, H. Hase +2
We present gamma-ray observations with the LAT on board the Fermi Gamma-Ray Telescope of the nearby radio galaxy Centaurus~A. The previous EGRET detection is confirmed, and the loc…
PKS 1502+106: a new and distant gamma-ray blazar in outburst discovered by the Fermi Large Area Telescope
The Fermi LAT Collaboration, the Multifrequency Campaing Collaboration
The Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope discovered a rapid (about 5 days duration), high-energy (E >100 MeV) gamma-ray outburst from a source id…
Radio-Loud Narrow-Line Seyfert 1 as a New Class of Gamma-Ray AGN
LAT Collaboration, G. Ghisellini, L. Maraschi +1
We report the discovery with Fermi/LAT of gamma-ray emission from three radio-loud narrow-line Seyfert 1 galaxies: PKS 1502+036 (z=0.409), 1H 0323+342 (z=0.061) and PKS 2004-447 (z…
