Latest results of ultra-high-energy cosmic ray measurements with prototypes of the Fluorescence detector Array of Single-pixel Telescopes (FAST)

Posted by Chicago

Kavli Affiliate: Paolo Privitera | First 5 Authors: Toshihiro Fujii, Justin Albury, Jose Bellido, Ladislav Chytka, John Farmer | Summary: The origin and nature of ultra-high-energy cosmic rays (UHECRs) remain an open question in astroparticle physics. Motivated by the need for an unprecedented aperture for further advancements, the Fluorescence detector Array of Single-pixel Telescopes (FAST) […]

The Phases of Non-supersymmetric Gauge Theories: the $SO(N_c)$ Case Study

Posted by klaurent Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Csaba Csáki, Andrew Gomes, Hitoshi Murayama, Ofri Telem, | Summary: We investigate the IR phases of non-supersymmetric (non-SUSY) $SO(N_c)$ gauge theories with $N_F$ fermions in the vector representation obtained by perturbing the SUSY theory with anomaly mediated SUSY breaking (AMSB). We find that of the wide variety […]

The relative contribution to heavy metals production from binary neutron star mergers and neutron star-black hole mergers

Posted by klaurent MIT

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Hsin-Yu Chen, Salvatore Vitale, Francois Foucart, , | Summary: The origin of the heavy elements in the Universe is not fully determined. Neutron star-black hole (NSBH) and {binary neutron star} (BNS) mergers may both produce heavy elements via rapid neutron-capture (r-process). We use the recent detection of […]

The Stellar Initial Mass Function and Population Properties of M89 from Optical and NIR Spectroscopy: Addressing Biases in Spectral Index Analysis

Posted by Chicago

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Ilaria Lonoce, Anja Feldmeier-Krause, Wendy L. Freedman, , | Summary: The complexity of constraining the stellar initial mass function (IMF) in early-type galaxies cannot be overstated, given the necessity of both very high signal-to-noise (S/N) data and the difficulty of breaking the strong degeneracies that occur […]
