EM counterparts of structured jets from 3D GRMHD simulations
Adithan Kathirgamaraju, Alexander Tchekhovskoy, Dimitrios Giannios +1
GW170817/GRB170817A has offered unprecedented insight into binary neutron star post-merger systems. Its Prompt and afterglow emission imply the presence of a tightly collimated rel…
Prediction of the second peak in the afterglow of GW170817
Maxim V. Barkov, Adithan Kathirgamaraju, Yonggang Luo +2
We performed calculations of the late radio and X-ray afterglow of GRB/GW170817 in the cocoon-jet paradigm, predicting the appearance of a second peak in the afterglow light curve…
A Decline in the X-ray through Radio Emission from GW170817 Continues to Support an Off-Axis Structured Jet
K. D. Alexander, R. Margutti, P. K. Blanchard +17
We present new observations of the binary neutron star merger GW170817 at days post-merger, at radio (Karl G. Jansky Very Large Array; VLA), X-ray (Chandra X-ra…
The Binary Neutron Star event LIGO/VIRGO GW170817 a hundred and sixty days after merger: synchrotron emission across the electromagnetic spectrum
Raffaella Margutti, K. D. Alexander, X. Xie +17
We report deep Chandra, HST and VLA observations of the binary neutron star event GW170817 at d after merger. These observations show that GW170817 has been steadily bright…
