A Radio Pinwheel Emanating from WR147
Luis F. Rodríguez, Jane Arthur, Gabriela Montes +2
Wolf-Rayet (WR) stars are evolved massive stars, presumably on their way to becoming supernova. They are characterized by high luminosities and fast and dense stellar winds. We hav…
The Properties of Short gamma-ray burst Jets Triggered by neutron star mergers
Ariadna Murguia-Berthier, Enrico Ramirez-Ruiz, Gabriela Montes +6
The most popular model for short gamma-ray bursts (sGRBs) involves the coalescence of binary neutron stars. Because the progenitor is actually hidden from view, we must consider un…
Lessons from the Onset of a Common Envelope Episode: the Remarkable M31 2015 Luminous Red Nova Outburst
Morgan MacLeod, Phillip Macias, Enrico Ramirez-Ruiz +3
This paper investigates the recent stellar merger transient M31LRN 2015 in the Andromeda galaxy. We analyze published optical photometry and spectroscopy along with a Hubble Space…
Transport and mixing of r-process elements in neutron star binary merger blast waves
Gabriela Montes, Enrico Ramirez-Ruiz, Jill Naiman +2
The r-process nuclei are robustly synthesized in the material ejected during a neutron star binary merger (NSBM), as tidal torques transport angular momentum and energy through the…
Diversity Of Short Gamma-Ray Burst Afterglows From Compact Binary Mergers Hosting Pulsars
Cole Holcomb, Enrico Ramirez-Ruiz, Fabio De Colle +1
Short gamma-ray bursts (sGRBs) are widely believed to result from the mergers of compact binaries. This model predicts an afterglow that bears the characteristic signatures of a co…
The Peculiar Radio Source M17 JVLA 35
L. F. Rodriguez, C. Carrasco-Gonzalez, G. Montes +1
M17 JVLA 35 is a radio source detected in projection against the M17 HII region. In recent observations, its spectrum between 4.96 and 8.46 GHz was found to be positive and very st…
Necessary Conditions for Short Gamma-Ray Burst Production in Binary Neutron Star Mergers
Ariadna Murguia-Berthier, Gabriela Montes, Enrico Ramirez-Ruiz +2
The central engine of short gamma-ray bursts (sGRBs) is hidden from direct view, operating at a scale much smaller than that probed by the emitted radiation. Thus we must infer its…
Understanding the Unusual X-Ray Emission Properties of the Massive, Close Binary WR 20a: A High Energy Window into the Stellar Wind Initiation Region
Gabriela Montes, Enrico Ramirez-Ruiz, Fabio De Colle +1
The problem of explaining the X-ray emission properties of the massive, close binary WR 20a is discussed. Located near the cluster core of Westerlund 2, WR 20a is composed of two n…
Compact radio sources in M17
Luis F. Rodriguez, Ricardo F. Gonzalez, Gabriela Montes +3
The classic HII region M17 is one of the best studied across the electromagnetic spectrum. We present sensitive, high angular resolution observations made with the Jansky Very Larg…
A model for the thermal radio-continuum emission from radiative shocks in colliding stellar winds
G. Montes, R. F. Gonzalez, J. Canto +2
Aims. The interaction of two isotropic stellar winds is studied in order to calculate the free-free emission from the wind collision region. The effects of the binary separation an…
The Rare 23.1-GHz Methanol Masers in NGC 7538 IRS 1
Roberto Galván-Madrid, Gabriela Montes, Edgar A. Ramírez +3
We present high angular resolution (FWHM_beam < 0.2") observations of the 23.1-GHz methanol (CH_3OH) transition toward the massive-star forming region NGC 7538 IRS 1. The two veloc…
Disentangling the Nature of the Radio Emission in Wolf Rayet Stars
Gabriela Montes, Miguel A. Perez-Torres, Antxon Alberdi +1
We present quasi-simultaneous, multi-frequency VLA observations at 4.8, 8.4, and 22.5 GHz, of a sample of 13 Wolf Rayet (WR) stars, aimed at disentangling the nature of their radio…
