Coronal Properties of the Seyfert 1.9 Galaxy MCG -05-23-016 Determined from Hard X-ray Spectroscopy with NuSTAR
M. Baloković, G. Matt, F. A. Harrison +15
Measurements of the high-energy cut-off in the coronal continuum of active galactic nuclei have long been elusive for all but a small number of the brightest examples. We present a…
Early-time VLA observations and broad-band afterglow analysis of the Fermi-LAT detected GRB 130907A
Péter Veres, Alessandra Corsi, Dale A. Frail +2
We present multi-wavelength observations of the hyper-energetic gamma-ray burst (GRB) 130907A, a Swift-discovered burst with early radio observations starting at hr aft…
Iron K and Compton hump reverberation in SWIFT J2127.4+5654 and NGC 1365 revealed by NuSTAR and XMM-Newton
E. Kara, A. Zoghbi, A. Marinucci +13
In the past five years, a flurry of X-ray reverberation lag measurements of accreting supermassive black holes have been made using the XMM-Newton telescope in the 0.3-10 keV energ…
Revised upper limit to energy extraction from a Kerr black hole
Jeremy D. Schnittman
We present a new upper limit on the energy that may be extracted from a Kerr black hole by means of particle collisions in the ergosphere (i.e., the "collisional Penrose process").…
The hydrogen-poor superluminous supernova iPTF13ajg and its host galaxy in absorption and emission
Paul M. Vreeswijk, Sandra Savaglio, Avishay Gal-Yam +24
We present imaging and spectroscopy of a hydrogen-poor superluminous supernova (SLSN) discovered by the intermediate Palomar Transient Factory: iPTF13ajg. At a redshift of z=0.7403…
Discovery of a Neutron Star Oscillation Mode During a Superburst
Tod Strohmayer, Simin Mahmoodifar
Neutron stars are among the most compact objects in the universe and provide a unique laboratory for the study of cold ultra-dense matter. While asteroseismology can provide a powe…
