Probing the Active Massive Black Hole Candidate in the Center of NGC 404 with VLBI
Z. Paragi, S. Frey, P. Kaaret +3
Recently Nyland et al. (2012) argued that the radio emission observed in the center of the dwarf galaxy NGC 404 originates in a low-luminosity active galactic nucleus (LLAGN) power…
A relativistic iron emission line from the neutron star low-mass X-ray binary GX 3+1
S. Piraino, A. Santangelo, P. Kaaret +7
We present the results of a spectroscopic study of the Fe Kα emission of the persistent neutron-star atoll low-mass X-ray binary and type I X-ray burster GX 3+1 with the EPIC-PN on…
Discovery of TeV Gamma Ray Emission from Tycho's Supernova Remnant
V. A. Acciari, E. Aliu, T. Arlen +82
We report the discovery of TeV gamma-ray emission from the Type Ia supernova remnant (SNR) G120.1+1.4, known as Tycho's supernova remnant. Observations performed in the period 2008…
VLBI observations of SN 2008iz: I. Expansion velocity and limits on anisotropic expansion
A. Brunthaler, I. Marti-Vidal, K. M. Menten +9
We present observations of the recently discovered supernova 2008iz in M82 with the VLBI High Sensitivity Array at 22 GHz, the Very Large Array at frequencies of 1.4, 4.8, 8.4, 22…
Radio observations of NGC 6388: an upper limit on the mass of its central black hole
D. Cseh, P. Kaaret, S. Corbel +4
We present the results of deep radio observations with the Australia Telescope Compact Array (ATCA) of the globular cluster NGC 6388. We show that there is no radio source detected…
Measuring the Accreting Stellar and Intermediate Mass Black Hole Populations in the Galaxy and Local Group
Jonathan Grindlay, Didier Barret, Tomaso Belloni +23
The population of stellar black holes (SBHs) in the Galaxy and galaxies generally is poorly known in both number and distribution. SBHs are the fossil record of the massive stars i…
Discovery of very high energy gamma rays from PKS 1424+240 and multiwavelength constraints on its redshift
The VERITAS Collaboration, V. A. Acciari, The Fermi Collaboration +4
We report the first detection of very-high-energy (VHE) gamma-ray emission above 140 GeV from PKS 1424+240, a BL Lac object with an unknown redshift. The photon spectrum above 140…
Chandra Localizations and Spectra of INTEGRAL Sources in the Galactic Plane: The Cycle 9 Sample
John A. Tomsick, Sylvain Chaty, Jerome Rodriguez +2
We report on 0.3-10 keV X-ray observations by the Chandra X-ray Observatory of the fields of 22 sources that were discovered as hard X-ray (20-100 keV) sources by the INTEGRAL sate…
Identifications of Four INTEGRAL Sources in the Galactic Plane via Chandra Localizations
John A. Tomsick, Sylvain Chaty, Jerome Rodriguez +3
Hard X-ray imaging of the Galactic plane by the INTEGRAL satellite is uncovering large numbers of 20-100 keV "IGR" sources. We present results from Chandra, INTEGRAL, optical, and…
