A very-high-energy component deep in the Gamma-ray Burst afterglow
H. Abdalla R. Adam F. Aharonian F. Ait Benkhali E. O. Anguener M. Arakawa, C. Arcaro, C. Armand +219
Gamma-ray bursts (GRBs) are brief flashes of gamma rays, considered to be the most energetic explosive phenomena in the Universe. The emission from GRBs comprises a short (typicall…
Theoretical priors in scalar-tensor cosmologies: Thawing quintessence
Carlos García-García, Emilio Bellini, Pedro G. Ferreira +2
The late time acceleration of the Universe can be characterized in terms of an extra, time dependent, component of the universe -- dark energy. The simplest proposal for dark energ…
Gas flow and accretion via spiral streamers and circumstellar disks in a young binary protostar
Felipe O. Alves, Paola Caselli, Josep M. Girart +4
The majority of stars are part of gravitationally bound stellar systems, such as binaries. Observations of protobinary systems constrain the conditions that lead to stellar multipl…
-attractor dark energy in view of next-generation cosmological surveys
Carlos García-García, Pilar Ruíz-Lapuente, David Alonso +1
The -attractor inflationary models are nowadays favored by CMB Planck observations. Their similarity with canonical quintessence models motivates the exploration of a common fra…
Spatially-resolved stellar populations and kinematics with KCWI: probing the assembly history of the massive early-type galaxy NGC 1407
Anna Ferre-Mateu, Duncan A. Forbes, Richard M. McDermid +2
Using the newly commissioned KCWI instrument on the Keck-II telescope, we analyse the stellar kinematics and stellar populations of the well-studied massive early-type galaxy (ETG)…
Interplanetary spread of solar energetic protons near a high-speed solar wind stream
Nicolas Wijsen, Angels Aran, Jens Pomoell +1
We study how a high-speed solar wind stream embedded in a slow solar wind influences the spread of solar energetic protons in interplanetary space. To model the energetic protons,…
