The Imprint of The Extragalactic Background Light in the Gamma-Ray Spectra of Blazars
LAT Collaboration
The light emitted by stars and accreting compact objects through the history of the Universe is encoded in the intensity of the extragalactic background light (EBL). Knowledge of t…
Opposite polarity field with convective downflow and its relation to magnetic spines in a sunspot penumbra
G. B. Scharmer, J. de la Cruz Rodríguez, P. Sütterlin +1
We discuss NICOLE inversions of Fe I 630.15 nm and 630.25 nm Stokes spectra from a sunspot penumbra recorded with the CRISP imaging spectropolarimeter on the Swedish 1-m Solar Tele…
3D Temperature Mapping of Solar Photospheric Fine Structure Using Ca II H Filtergrams
V. M. J. Henriques
Context. The wings of the Ca II H and K lines provide excellent photospheric temperature diagnostics. At the Swedish 1-meter Solar Telescope the blue wing of Ca II H is scanned wit…
Dark Matter and Fundamental Physics with the Cherenkov Telescope Array
M. Doro, J. Conrad, D. Emmanoulopoulos +30
The Cherenkov Telescope Array (CTA) is a project for a next-generation observatory for very high energy (GeV-TeV) ground-based gamma-ray astronomy, currently in its design phase, a…
Non-local thermodynamic equilibrium inversions from a 3D MHD chromospheric model
Jaime de la Cruz Rodríguez, Hector Socas-Navarro, Mats Carlsson +1
The structure of the solar chromosphere is believed to be governed by magnetic fields, even in quiet-Sun regions that have a relatively weak photospheric field. During the past dec…
Limits on Large Extra Dimensions Based on Observations of Neutron Stars with the Fermi-LAT
Bijan Berenji, Elliott Bloom, Johann Cohen-Tanugi
We present limits for the compactification scale in the theory of Large Extra Dimensions (LED) proposed by Arkani-Hamed, Dimopoulos, and Dvali. We use 11 months of data from the Fe…
