Non-Abelian gauged supergravities as double copies
Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1
Scattering amplitudes have the potential to provide new insights to the study of supergravity theories with gauged R-symmetry and Minkowski vacua. Such gaugings break supersymmetry…
Centrality and transverse momentum dependence of -meson production at mid-rapidity in Au+Au collisions at
STAR Collaboration, J. Adam, L. Adamczyk +347
We report a new measurement of -meson production at mid-rapidity (\,\,1) in Au+Au collisions at utilizing the Heavy Flavor Tracke…
A VLA-GMRT Look at 11 Powerful FR II Quasars
S. Vaddi, P. Kharb, R. A. Daly +5
We present results from 1.4 and 5 GHz observations at matched resolution with the Karl G. Jansky Very Large Array (VLA) of 11 powerful 3C FR II quasars. We examine the 11 quasars a…
IRAM and Gaia views of multi-episodic star formation in IC1396A: The origin and dynamics of the Class 0 protostar at the edge of an HII region
Aurora Sicilia-Aguilar, Nimesh Patel, Min Fang +3
(Abridged) IC1396A is a cometary globule containing the Class 0 source IC1396A-PACS-1. We use IRAM 30m and Gaia DR2 data to explore the star-formation history of IC1396A and invest…
High-resolution spectroscopy of Boyajian's star during optical dimming events
M. J. Martínez González, C. González-Fernández, A. Asensio Ramos +13
Boyajian's star is an apparently normal main sequence F-type star with a very unusual light curve. The dipping activity of the star, discovered during the Kepler mission, presents…
Probing the Cyclotron line characteristics of 4U 1538-522 using AstroSat-LAXPC
Varun, Chandreyee Maitra, Pragati Pradhan +2
We report the first report on cyclotron line studies with the LAXPC instrument onboard AstroSat of the High mass X-ray Binary pulsar 4U 1538-52. During the observation of source wh…
