Supergiant X-ray binaries observed by Suzaku

A. Bodaghee, J. A. Tomsick, J. Rodriguez +4

Suzaku observations are presented for the high-mass X-ray binaries IGR J16207-5129 and IGR J17391-3021 (=XTE J1739-302). For IGR J16207-5129, we provide the first X-ray broadband (…

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)…

SN 2010ay is a Luminous and Broad-lined Type Ic Supernova within a Low-metallicity Host Galaxy

Nathan E. Sanders, A. M. Soderberg, S. Valenti +38

We report on our serendipitous pre-discovery detection and detailed follow-up of the broad-lined Type Ic supernova (SN) 2010ay at z = 0.067 imaged by the Pan-STARRS1 3pi survey jus…

Clustering between high-mass X-ray binaries and OB associations in the Milky Way

Arash Bodaghee, John A. Tomsick, Jerome Rodriguez +1

We present the first direct measurement of the spatial cross-correlation function of high-mass X-ray binaries (HMXBs) and active OB star-forming complexes in the Milky Way. This re…

First simultaneous multi-wavelength observations of the black hole candidate IGR J17091-3624: ATCA, INTEGRAL, Swift, and RXTE views of the 2011 outburst

J. Rodriguez, S. Corbel, I. Caballero +5

We present the results of the first four (quasi-)simultaneous radio (ATCA), X-ray (Swift, RXTE), and Gamma-ray (INTEGRAL) observations of the black hole candidate IGR J17091-3624,…

X-ray Observations of Radio Transients without Optical Hosts

Steve Croft, John A. Tomsick, Geoffrey C. Bower

We present a 50 ks Chandra ACIS-I X-ray observation of the Bower et al. VLA archival field. The observations reach a limiting sensitivity of ~1E-4 counts/s, corresponding to a flux…

Panchromatic Observations of SN 2011dh Point to a Compact Progenitor Star

Alicia M. Soderberg, R. Margutti, B. A. Zauderer +32

We report the discovery and detailed monitoring of X-ray emission associated with the Type IIb SN 2011dh using data from the Swift and Chandra satellites, placing it among the best…

Discovery of the infrared counterpart of CXOU J174437.3-323222 in the field of IGR J17448-3232: a blazar candidate viewed through the Galactic centre?

P. A. Curran, S. Chaty, J. A. Zurita Heras +2

We present our near infrared ESO-NTT Ks band observations of the field of IGR J17448-3232 which show no extended emission consistent with the SNR but in which we identify a new cou…

Discovery and evolution of the new black hole candidate Swift J1539.2-6227 during its 2008 outburst

H. A. Krimm, J. A. Tomsick, C. B. Markwardt +4

We report on the discovery by the Swift Gamma-Ray Burst Explorer of the black hole candidate Swift J1539.2-6227 and the subsequent course of an outburst beginning in November 2008…
