Identifying Elusive Electromagnetic Counterparts to Gravitational Wave Mergers: an end-to-end simulation

Samaya Nissanke, Mansi Kasliwal, Alexandra Georgieva

Combined gravitational-wave (GW) and electromagnetic (EM) observations of compact binary mergers should enable detailed studies of astrophysical processes in the strong-field gravi…

Linking accretion flow and particle acceleration in jets. I. New relativistic magnetohydrodynamical jet solutions including gravity

Peter Polko, David L. Meier, Sera Markoff

We present a new, approximate method for modelling the acceleration and collimation of relativistic jets in the presence of gravity. This method is self-similar throughout the comp…

Contribution of the accretion disk, hot corona, and obscuring torus to the luminosity of Seyfert galaxies: INTEGRAL and Spitzer observations

S. Sazonov, S. P. Willner, A. D. Goulding +12

We estimate the relative contributions of the supermassive black hole (SMBH) accretion disk, corona, and obscuring torus to the bolometric luminosity of Seyfert galaxies, using Spi…

Coherent Radiation from Extensive Air Showers in the Ultra-High Frequency Band

Jaime Alvarez-Muñiz, Washington R. Carvalho, Andrés Romero-Wolf +2

Using detailed Monte Carlo simulations we have characterized the features of the radio emission of inclined air showers in the Ultra-High Frequency band (300 MHz - 3 GHz). The Four…

A Multi-Wavelength Study of the Jet, Lobes and Core of the Quasar PKS 2101-490

L. E. H. Godfrey, G. V. Bicknell, J. E. J. Lovell +9

We present a detailed study of the X-ray, optical and radio emission from the jet, lobes and core of the quasar PKS 2101-490 as revealed by new Chandra, HST and ATCA images. We ext…

The characterization of the distant blazar GB6 J1239+0443 from flaring and low activity periods

L. Pacciani, I. Donnarumma, K. D. Denney +64

In 2008 AGILE and Fermi detected gamma-ray flaring activity from the unidentified EGRET source 3EG J1236+0457, recently associated with a flat spectrum radio quasar GB6 J1239+0443…

Limits on the event rates of fast radio transients from the V-FASTR experiment

Randall B. Wayth, Steven J. Tingay, Adam T. Deller +4

We present the first results from the V-FASTR experiment, a commensal search for fast transient radio bursts using the Very Long Baseline Array (VLBA). V-FASTR is unique in that th…

Multi-wavelength Observations of the Radio Magnetar PSR J1622-4950 and Discovery of its Possibly Associated Supernova Remnant

Gemma E. Anderson, B. M. Gaensler, Patrick O. Slane +29

We present multi-wavelength observations of the radio magnetar PSR J1622-4950 and its environment. Observations of PSR J1622-4950 with Chandra (in 2007 and 2009) and XMM (in 2011)…

Double Compact Objects I: The Significance Of The Common Envelope On Merger Rates

Michal Dominik, Krzysztof Belczynski, Christopher Fryer +5

The last decade of observational and theoretical developments in stellar and binary evolution provides an opportunity to incorporate major improvements to the predictions from popu…

Discovery of a Meter-Wavelength Radio Transient in the SWIRE Deep Field: 1046+59

T. R. Jaeger, S. D. Hyman, N. E. Kassim +1

We report the results of a low frequency radio variability and slow transient search using archival observations from the Very Long Array. We selected six 325 MHz radio observation…
