Interplanetary magnetic flux rope observed at ground level by HAWC
S. Akiyama, R. Alfaro, C. Alvarez +59
We report the ground-level detection of a Galactic Cosmic-Ray (GCR) flux enhancement lasting 17 hr and associated with the passage of a magnetic flux rope (MFR) over the Ear…
Galactic Cosmic Ray Sun Shadow during the declining phase of cycle 24 observed by HAWC
Alejandro Lara, Paulina Colin, K. P. Arunbabu +1
The High Altitude Water Cherenkov (HAWC) array is sensitive to high energy Cosmic Rays (CR) in the to TeV energy range, making it possible to construct maps of…
On the Shock Source of Sustained Gamma-Ray Emission from the Sun
N Gopalswamy, P. Makela, S. Yashiro +3
It has recently been shown that the spatially and temporally extended gamma-ray emission in solar eruptions are caused by greater than 300 MeV protons precipitating on the Sun from…
Fermi, Wind, and SOHO Observations of Sustained Gamma-Ray Emission from the Sun
N. Gopalswamy, P. Makela, S. Yashiro +4
We report on the linear relationship between the durations of two types of electromagnetic emissions associated with shocks driven by coronal mass ejections: sustained gamma-ray em…
Numerical simulations of ICME-ICME interactions
Tatiana Niembro, Alejandro Lara, Ricardo F. González +1
We present hydrodynamical simulations of interacting Coronal Mass Ejections in the Interplanetary medium (ICMEs). In these events, two consecutive CMEs are launched from the Sun in…
The Galactic cosmic-ray Sun shadow observed by HAWC
O. Enriquez, A. Lara
The magnetic field of the Solar corona is difficult to measure directly. However, indirect observations of the solar corona are possible using the deficit in flux of cosmic rays co…
