Fermi-LAT Observations of the Gamma-ray Burst GRB 130427A
LAT collaboration, GBM collaboration
The observations of the exceptionally bright gamma-ray burst (GRB) 130427A by the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope provide constraints on the nature…
Inner Heliospheric Evolution of a "Stealth" CME Derived From Multi-view Imaging and Multipoint In--situ observations: I. Propagation to 1 AU
T. Nieves-Chinchilla, A. Vourlidas, G. Stenborg +4
Coronal mass ejections (CMEs) are the main driver of Space Weather. Therefore, a precise forecasting of their likely geo-effectiveness relies on an accurate tracking of their morph…
A Plasma β Transition Within a Propagating Flux Rope
Neel P. Savani, A. Vourlidas, D. Shiota +4
We present a 2.5D MHD simulation of a magnetic flux rope (FR) propagating in the heliosphere and investigate the cause of the observed sharp plasma beta transition. Specifically, w…
Einstein@Home discovery of four young gamma-ray pulsars in Fermi LAT data
H. J. Pletsch, L. Guillemot, B. Allen +15
We report the discovery of four gamma-ray pulsars, detected in computing-intensive blind searches of data from the Fermi Large Area Telescope (LAT). The pulsars were found using a…
Determining heating time scales in solar active region cores from AIA/SDO Fe XVIII images
Ignacio Ugarte-Urra, Harry P. Warren
We present a study of the frequency of transient brightenings in the core of solar active regions as observed in the Fe XVIII line component of AIA/SDO 94 A filter images. The Fe X…
A Tidal Disruption Event in a Nearby Galaxy Hosting an Intermediate Mass Black Hole
Davide Donato, Stephen Bradley Cenko, Stefano Covino +9
We report the serendipitous discovery of a bright point source flare in the Abell cluster 1795 with archival EUVE and Chandra observations. Assuming the EUVE emission is associated…
