Cascading Constraints from Neutrino Emitting Blazars: The case of TXS 0506+056
Anita Reimer, Markus Boettcher, Sara Buson
We present a procedure to generally constrain the environments of neutrino-producing sites in photomeson production models of jetted Active Galactic Nuclei (AGN) where any origin o…
X-ray and optical monitoring of the December 2017 outburst of the Be/X-ray binary AX J0049.4-7323
L. Ducci, C. Malacaria, P. Romano +5
AX J0049.4-7323 is a Be/X-ray binary that shows an unusual and poorly understood optical variability that consists of periodic and bright optical outbursts, simultaneous with X-ray…
High-resolution Charge Exchange Spectra with L-shell Nickel Show Striking Differences from Models
G. L. Betancourt-Martinez, P. Beiersdorfer, G. V. Brown +7
We present the first high-resolution laboratory spectra of X-ray emission following L-shell charge exchange between nickel ions and neutral H2 and He. We employ the commonly used c…
Anti-glitches in the Ultraluminous Accreting Pulsar NGC 300 ULX-1 Observed with NICER
Paul S. Ray, Sebastien Guillot, Wynn C. G. Ho +13
We present evidence for three spin-down glitches (or `anti-glitches') in the ultraluminous accreting X-ray pulsar NGC 300 ULX-1 in timing observations made with the Neutron Star In…
A Fermi Gamma-ray Burst Monitor Search for Electromagnetic Signals Coincident with Gravitational-Wave Candidates in Advanced LIGO's First Observing Run
ray Burst Monitor Team, The LIGO Scientific Collaboration, the Virgo Collaboration +1160
We present a search for prompt gamma-ray counterparts to compact binary coalescence gravitational wave (GW) candidates from Advanced LIGO's first observing run (O1). As demonstrate…
Detection of polarized gamma-ray emission from the Crab nebula with Hitomi Soft Gamma-ray Detector
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +191
We present the results from the Hitomi Soft Gamma-ray Detector (SGD) observation of the Crab nebula. The main part of SGD is a Compton camera, which in addition to being a spectrom…
