Kavli Affiliate: George Efstathiou | First 5 Authors: Christian Hellum Bye, Stephen K. N. Portillo, Anastasia Fialkov, , | Summary: Considerable observational efforts are being dedicated to measuring the sky-averaged (global) 21-cm signal of neutral hydrogen from Cosmic Dawn and the Epoch of Reionization. Deriving observational constraints on the astrophysics of this era requires modelling […]

Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: The BESIII Collaboration has observed a candidate for a $c bar c s bar u$ tetraquark $Z_{cs}$ at $(3982.5^{+1.8}_{-2.6} pm 2.1)$ MeV and width $(12.8^{+5.3}_{-4.4} pm 3.0)$ MeV, while the LHCb Collaboration has observed a $Z_{cs}$ candidate […]
Kavli Affiliate: Tom Melia | First 5 Authors: Andrew J. Larkoski, Tom Melia, , , | Summary: Despite being the overwhelming majority of events produced in hadron or heavy ion collisions, minimum bias events do not enjoy a robust first-principles theoretical description as their dynamics are dominated by low-energy quantum chromodynamics. In this paper, we […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Kai Murai, Hiromasa Nakatsuka, , | Summary: Primordial black hole (PBH) is a fascinating candidate for the origin of binary merger events observed by LIGO-Virgo collaboration. The spatial distribution of PBHs at formation is an important feature to estimate the merger rate. We investigate the […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ryan Mckinven, Daniele Michilli, Kiyoshi W. Masui, Davor Cubranic, B. M. Gaensler | Summary: Polarimetric observations of Fast Radio Bursts (FRBs) are a powerful resource for better understanding these mysterious sources by directly probing the emission mechanism of the source and the magneto-ionic properties of its […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: Nolan Grieves, François Bouchy, Monika Lendl, Theron Carmichael, Ismael Mireles | Summary: We report the discovery of five transiting companions near the hydrogen-burning mass limit in close orbits around main sequence stars originally identified by the Transiting Exoplanet Survey Satellite (TESS) as TESS Objects of Interest […]
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) […]
Kavli Affiliate: R. Morris | First 5 Authors: J. R. Morris, , , , | Summary: A class of noncanonical effective potentials is introduced allowing stable, radially symmetric, solutions to first order Bogomol’nyi equations for a real scalar field in a fixed spacetime background. This class of effective potentials generalizes those found previously by Bazeia, […]
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 […]
