Detection of Cosmic Structures using the Bispectrum Phase. II. First Results from Application to Cosmic Reionization Using the Hydrogen Epoch of Reionization Array

Posted by klaurent MIT

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Nithyanandan Thyagarajan, Chris L. Carilli, Bojan Nikolic, James Kent, Andrei Mesinger | Summary: Characterizing the epoch of reionization (EoR) at $zgtrsim 6$ via the redshifted 21 cm line of neutral Hydrogen (HI) is critical to modern astrophysics and cosmology, and thus a key science goal of […]

Orbital Modulation of Gamma Rays from PSR~J2339$-$0533

Posted by klaurent Stanford

Kavli Affiliate: Roger W. Romani | First 5 Authors: Hongjun An, Roger W. Romani, Matthew Kerr, , | Summary: We report on orbital modulation of the 100-600 MeV gamma-ray emission of the $P_{rm B}=4.6$ hr millisecond pulsar binary PSR J2339$-$0533 using 11 yr of Fermi Large Area Telescope data. The modulation has high significance (chance […]

TESS Data for Asteroseismology: Timing verification

Posted by klaurent MIT

Kavli Affiliate: Edward Morgan | Summary:The Transiting Exoplanet Survey Satellite (TESS) is NASA’s latest space telescope dedicated to the discovery of transiting exoplanets around nearby stars. Besides the main goal of the mission, asteroseismology is an important secondary goal and very relevant for the high-quality time series that TESS will make during its two year […]

Muons in supernovae: implications for the axion-muon coupling

Posted by klaurent Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Robert Bollig, William DeRocco, Peter W. Graham, Hans-Thomas Janka, | Summary: The high temperature and electron degeneracy attained during a supernova allow for the formation of a large muon abundance within the core of the resulting proto-neutron star. If new pseudoscalar degrees of freedom have large […]

VERITAS Discovery of VHE Emission from the Radio Galaxy 3C 264: A Multi-Wavelength Study

Posted by klaurent Chicago

Kavli Affiliate: Scott P. Wakely| First 5 Authors: A. Archer, A. Archer, , , | Summary:The radio source 3C 264, hosted by the giant elliptical galaxy NGC 3862, was observed with VERITAS between February 2017 and May 2019. These deep observations resulted in the discovery of very-high-energy (VHE; E $>100$ GeV) $γ$-ray emission from this […]

S-duality and correlation functions at large R-charge

Posted by klaurent Tokyo

Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Shunsuke Maeda, Domenico Orlando, Susanne Reffert, Masataka Watanabe | Summary: We study the ratio of pairs of adjacent correlators of Coulomb-branch operators in $SU(2)$ $mathcal{N}=2$ SQCD with four flavors within the framework of the Large Quantum Number Expansion. Capitalizing on the order-by-order S-duality invariance of […]

Witten Anomaly in 4d Heterotic Compactificaitons with N = 2 Supersymmetry

Posted by klaurent Tokyo

Kavli Affiliate: Taizan Watari | Summary:We showed that there is no SU(2) Witten anomaly in a large class of 4d N = 2 supersymmetric Heterotic string compactifications. The consistency conditions we consider are the modularity of the new supersymmetric index, the integrality of BPS indices, and the discrete Peccei-Quinn shift symmetries. We also found an […]
