Cosmic Reionization on Computers: Evolution of the Flux Power Spectrum

Kavli Affiliate: Nickolay Gnedin | First 5 Authors: Nishant Mishra, Nickolay Gnedin, , , | Summary: We explore the evolution of the flux power spectrum in the Cosmic Reionization On Computers (CROC) simulations. We find that, contrary to some previous studies, the shape of the flux power spectrum is rather insensitive to the timing of […]

How low can you go? SN 2018zd as a low-mass Fe core-collapse supernova

Kavli Affiliate: Subo Dong | First 5 Authors: E. Callis, M. Fraser, A. Pastorello, Subo Dong, S. J. Brennan | Summary: We present spectroscopy and photometry of SN 2018zd, a Type IIP core-collapse supernova with signatures of interaction with circumstantial material in its earliest spectra. High ionization lines, the earmark of shock breakout, are not […]

Primordial Black Holes from CDM Isocurvature

Kavli Affiliate: Misao Sasaki | First 5 Authors: Samuel Passaglia, Misao Sasaki, , , | Summary: We show that primordial black holes can be produced from the collapse of large isocurvature perturbations of the cold dark matter. We develop a novel procedure to compute the resulting black hole abundance by studying matched perturbations of matter-only […]

Rotation and deformation of strangeon stars in the Lennard-Jones model

Kavli Affiliate: Lijing Shao | First 5 Authors: Yong Gao, Xiao-Yu Lai, Lijing Shao, Ren-Xin Xu, | Summary: The strong interactions at low energy scales determine the state of the supranuclear matter in the pulsar-like compact objects. It is proposed that the bulk strong matter could be composed of strangeons, which are quark clusters with […]

Automated Detection of Antenna Malfunctions in Large-N Interferometers: A Case Study with the Hydrogen Epoch of Reionization Array

Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Dara Storer, Joshua S. Dillon, Daniel C. Jacobs, Miguel F. Morales, Bryna J. Hazelton | Summary: We present a framework for identifying and flagging malfunctioning antennas in large radio interferometers. We outline two distinct categories of metrics designed to detect outliers along known failure modes of […]

The Effects of Dark Matter and Baryonic Physics on the Milky Way Subhalo Population in the Presence of the Large Magellanic Cloud

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Arka Banerjee, Susmita Adhikari, Yao-Yuan Mao, Risa H. Wechsler | Summary: Given recent developments in our understanding of the Large Magellanic Cloud’s (LMC) impact on the Milky Way’s (MW) dark matter subhalo population, we compare the signatures of dark matter and baryonic physics […]

AdS3’s with and without BTZ’s

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, , , , | Summary: This companion paper to arXiv:2109.00065 explores the interpretation of $AdS_3/CFT_2$ duality for $k=(R_{AdS}/lstr)^2<1$ in terms of "non-critical little string theory". We review the underlying fivebrane structure of 1/2-BPS backgrounds for string theory in both the critical dimension and […]

Gravitational Memory and Compact Extra Dimensions

Kavli Affiliate: Savdeep Sethi | First 5 Authors: Christian Ferko, Gautam Satishchandran, Savdeep Sethi, , | Summary: We develop a general formalism for treating radiative degrees of freedom near $mathscr{I}^{+}$ in theories with an arbitrary Ricci-flat internal space. These radiative modes are encoded in a generalized news tensor which decomposes into gravitational, electromagnetic, and scalar […]

Angular correlations of causally-coherent primordial quantum perturbations

Kavli Affiliate: Stephan S. Meyer | First 5 Authors: Craig Hogan, Stephan S. Meyer, , , | Summary: We consider the hypothesis that nonlocal, omnidirectional, causally-coherent quantum entanglement of inflationary horizons may account for some well-known measured anomalies of Cosmic Microwave Background (CMB) anisotropy on large angular scales. It is shown that causal coherence can […]
