Swift observations of two outbursts from the magnetar 4U 0142+61
R. F. Archibald, V. M. Kaspi, P. Scholz +3
4U 0142+61 is one of a small class of persistently bright magnetars. Here we report on a monitoring campaign of 4U 0142+61 from 2011 July 26 - 2016 June 12 using the Swift X-ray Te…
Observations of the Structure and Dynamics of the Inner M87 Jet
R. Craig Walker, Philip E. Hardee, Fred Davies +4
M87 is the best source in which to study a jet at high resolution in gravitational units because it has a very high mass black hole and is nearby. The angular size of the black hol…
Detection of Very Low-Frequency Quasi-Periodic Oscillations in the 2015 Outburst of V404 Cygni
D. Huppenkothen, G. Younes, A. Ingram +12
In June 2015, the black hole X-ray binary (BHXRB) V404 Cygni went into outburst for the first time since 1989. Here, we present a comprehensive search for quasi-periodic oscillatio…
X-ray Reflection and An Exceptionally Long Thermonuclear Helium Burst from IGR J17062-6143
L. Keek, W. Iwakiri, M. Serino +3
Thermonuclear X-ray bursts from accreting neutron stars power brief but strong irradiation of their surroundings, providing a unique way to study accretion physics. We analyze MAXI…
Learning About the Magnetar Swift J1834.9-0846 from its Wind Nebula
Jonathan Granot, Ramandeep Gill, George Younes +4
The first wind nebula around a magnetar was recently discovered in X-rays around Swift~J1834.90846. We study this magnetar's global energetics and the properties of its particle…
Two Distinct-Absorption X-Ray Components from Type IIn Supernovae: Evidence for Asphericity in the Circumstellar Medium
Satoru Katsuda, Keiichi Maeda, Aya Bamba +7
We present multi-epoch X-ray spectral observations of three Type IIn supernovae (SNe) 2005kd, 2006jd, and 2010jl, acquired with Chandra, XMM-Newton, Suzaku, and Swift. Previous ext…
