Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Joshua Eby, Satoshi Shirai, Yevgeny V. Stadnik, Volodymyr Takhistov, | Summary: Axions constituting dark matter (DM) are often considered to form a non-relativistic oscillating field. We explore bursts of relativistic axions from transient astrophysical sources, such as axion star explosions, where the sources are initially non-relativistic. […]
Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Joshua Eby, Satoshi Shirai, Yevgeny V. Stadnik, Volodymyr Takhistov, | Summary: Emission of relativistic axions from transient sources, such as axion star explosions, can lead to observable signatures. We show that axion bursts from collapsing axion stars can be detectable over the wide range of axion […]
Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Heather McCarrick, Erin Healy, Zeeshan Ahmed, Kam Arnold, Zachary Atkins | Summary: Advances in cosmic microwave background (CMB) science depend on increasing the number of sensitive detectors observing the sky. New instruments deploy large arrays of superconducting transition-edge sensor (TES) bolometers tiled densely into ever larger […]
Kavli Affiliate: John D. Silverman | First 5 Authors: Yoshiki Toba, Teng Liu, Tanya Urrutia, Mara Salvato, Junyao Li | Summary: We investigate the physical properties–such as the stellar mass, SFR, IR luminosity, X-ray luminosity, and hydrogen column density–of MIR galaxies and AGN at $z < 4$ in the 140 deg$^2$ field observed by SRG/eROSITA […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Itamar Reis, Rennan Barkana, Anastasia Fialkov, , | Summary: The 21-cm signal from cosmic dawn and the epoch of reionization (EoR) probes the characteristics of the high redshift galaxy population. Many of the astrophysical properties of galaxies at high redshifts are currently unconstrained due to the lack […]
Kavli Affiliate: Gregory Herczeg | First 5 Authors: Jeong-Eun Lee, Sieun Lee, Seonjae Lee, Kyung-Won Suh, Se-Hyung Cho | Summary: AGBs and YSOs often share the same domains in IR color-magnitude or color-color diagrams leading to potential mis-classification. We extracted a list of AGB interlopers from the published YSO catalogues using the periodogram analysis on […]
Kavli Affiliate: Brian Nord | First 5 Authors: Adam Shandonay, Robert Morgan, Keith Bechtol, Clecio R. Bom, Brian Nord | Summary: Searches for counterparts to multimessenger events with optical imagers use difference imaging to detect new transient sources. However, even with existing artifact detection algorithms, this process simultaneously returns several classes of false positives: false […]
Kavli Affiliate: C. L. Kuo | First 5 Authors: J. A. Sobrin, A. J. Anderson, A. N. Bender, B. A. Benson, D. Dutcher | Summary: SPT-3G is the third survey receiver operating on the South Pole Telescope dedicated to high-resolution observations of the cosmic microwave background (CMB). Sensitive measurements of the temperature and polarization anisotropies […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Vidya Muthukumar, Christos Thrampoulidis, , | Summary: The literature on "benign overfitting" in overparameterized models has been mostly restricted to regression or binary classification; however, modern machine learning operates in the multiclass setting. Motivated by this discrepancy, we study benign overfitting in multiclass linear classification. […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Csaba Csáki, Andrew Gomes, Hitoshi Murayama, Ofri Telem, | Summary: We demonstrate that $SO(N_{c})$ gauge theories with matter fields in the vector representation confine due to monopole condensation and break the $SU(N_{F})$ chiral symmetry to $SO(N_{F})$ via the quark bilinear. Our results are obtained by perturbing the […]
