Multi-wavelength spectropolarimetric observations of AR13724 performed by GRIS
C. Quintero Noda, J. C. Trelles Arjona, T. del Pino Alemán +10
Multi-line spectropolarimetric observations allow for the simultaneous inference of the magnetic field at different layers of the solar atmosphere and provide insight into how thes…
Non-Local Thermodynamic Equilibrium inversions of the Si I 10827 A spectral line
C. Quintero Noda, N. G. Shchukina, A. Asensio Ramos +4
Inferring the coupling of different atmospheric layers requires observing spectral lines sensitive to the atmospheric parameters, particularly the magnetic field vector, at various…
Mapping the hidden magnetic field of the quiet Sun
J. C. Trelles Arjona, M. J. Martínez González, B. Ruiz Cobo
The Sun is the only star where we can resolve the intricate magnetism that all convective stars harbor. Yet, more than 99% of its visible surface along the solar cycle (the so-call…
HAWC and Fermi-LAT Detection of Extended Emission from the Unidentified Source 2HWC J2006+341
A. Albert, R. Alfaro, C. Alvarez +71
The discovery of the TeV point source 2HWC J2006+341 was reported in the second HAWC gamma-ray catalog. We present a follow-up study of this source here. The TeV emission is best d…
3HWC: The Third HAWC Catalog of Very-High-Energy Gamma-ray Sources
A. Albert, R. Alfaro, C. Alvarez +104
We present a new catalog of TeV gamma-ray sources using 1523 days of data from the High Altitude Water Cherenkov (HAWC) observatory. The catalog represents the most sensitive surve…
HAWC J2227+610 and its association with G106.3+2.7, a new potential Galactic PeVatron
A. Albert, R. Alfaro, C. Alvarez +97
We present the detection of VHE gamma-ray emission above 100 TeV from HAWC J2227+610 with the HAWC observatory. Combining our observations with previously published results by VERI…
Constraints on the Emission of Gamma Rays from M31 with HAWC
HAWC Collaboration, A. Albert, R. Alfaro +82
Cosmic rays, along with stellar radiation and magnetic fields, are known to make up a significant fraction of the energy density of galaxies such as the Milky Way. When cosmic rays…
The Southern Wide-Field Gamma-Ray Observatory (SWGO): A Next-Generation Ground-Based Survey Instrument for VHE Gamma-Ray Astronomy
P. Abreu, A. Albert, R. Alfaro +95
We describe plans for the development of the Southern Wide-field Gamma-ray Observatory (SWGO), a next-generation instrument with sensitivity to the very-high-energy (VHE) band to b…
Diagnostic potential of the Ca II 8542A line for solar filaments
C. J. Díaz Baso, M. J. Martínez González, A. Asensio Ramos +1
In this study we explore the diagnostic potential of the chromospheric Ca II line at 8542A for studying the magnetic and dynamic properties of solar filaments. We have acquired hig…
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…
