Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Alina Sabyr, Carlos Sierra, J. Colin Hill, Jeffrey J. McMahon, | Summary: Deviations of the cosmic microwave background (CMB) energy spectrum from a perfect blackbody uniquely probe a wide range of physics, ranging from fundamental physics in the primordial Universe ($mu$-distortion) to late-time baryonic feedback processes […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Sijia Peng, Ru-Sen Lu, Ciriaco Goddi, Thomas P. Krichbaum, Zhiyuan Li | Summary: Faraday rotation is an important probe of the magnetic fields and magnetized plasma around active galactic nuclei (AGN) jets. We present a Faraday rotation measure image of the M87 jet between 85.2 GHz and […]
Kavli Affiliate: Brian D. Nord | First 5 Authors: Ashwin Samudre, Mircea Petrache, Brian D. Nord, Shubhendu Trivedi, | Summary: There has been much recent interest in designing symmetry-aware neural networks (NNs) exhibiting relaxed equivariance. Such NNs aim to interpolate between being exactly equivariant and being fully flexible, affording consistent performance benefits. In a separate […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Adaeze L. Ibik, Maria R. Drout, Bryan M. Gaensler, Paul Scholz, Navin Sridhar | Summary: The identification of persistent radio sources (PRSs) coincident with two repeating fast radio bursts (FRBs) supports FRB theories requiring a compact central engine. However, deep non-detections in other cases highlight the […]

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Shion Andrew, Calvin Leung, Alexander Li, Kiyoshi W. Masui, Bridget C. Andersen | Summary: The Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst (CHIME/FRB) Project has a new VLBI Outrigger at the Green Bank Observatory (GBO), which forms a 3300km baseline with CHIME operating at 400-800MHz. […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Tibor Dome, Simon May, Alex Laguë, David J. E. Marsh, Sarah Johnston | Summary: We study the implications of relaxing the requirement for ultralight axions to account for all dark matter in the Universe by examining mixed dark matter (MDM) cosmologies with axion fractions $f leq 0.3$ […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Xin-Chen He, Yi-Fu Cai, Xiao-Han Ma, Theodoros Papanikolaou, Emmanuel N. Saridakis | Summary: Ultra-light primordial black holes (PBHs) with masses $M_{rm PBH}<5times 10^8mathrm{g}$ can dominate transiently the energy budget of the Universe and reheat the Universe through their evaporation taking place before Big Bang Nucleosynthesis. The isocurvature […]
