HERA Phase I Limits on the Cosmic 21-cm Signal: Constraints on Astrophysics and Cosmology During the Epoch of Reionization

Kavli Affiliate: George Efstathiou | First 5 Authors: The HERA Collaboration, Zara Abdurashidova, James E. Aguirre, Paul Alexander, Zaki Ali | Summary: Recently, the Hydrogen Epoch of Reionization Array (HERA) collaboration has produced the experiment’s first upper limits on the power spectrum of 21-cm fluctuations at z~8 and 10. Here, we use several independent theoretical […]

The miniJPAS Survey: A Study on Wavelength Dependence of the Photon Response Non-uniformity of the JPAS-{it Pathfinder} Camera

Kavli Affiliate: Hu Zhan | First 5 Authors: Kai Xiao, Haibo Yuan, J. Varela, Hu Zhan, Jifeng Liu | Summary: Understanding the origins of small-scale flats of CCDs and their wavelength-dependent variations plays an important role in high-precision photometric, astrometric, and shape measurements of astronomical objects. Based on the unique flat data of 47 narrow-band […]

Exploring a PMT+SiPM Hybrid Optical Module for Next Generation Neutrino Telescopes

Kavli Affiliate: Zhuo Li | First 5 Authors: Fan Hu, Zhuo Li, Donglian Xu, , | Summary: Cosmic neutrinos are unique probes of the high energy universe. IceCube has discovered a diffuse astrophysical neutrino flux since 2013, but their origin remains elusive. The potential sources could include, for example, active galactic nuclei, gamma-ray bursts and […]

Matching higher symmetries across Intriligator-Seiberg duality

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yasunori Lee, Kantaro Ohmori, Yuji Tachikawa, , | Summary: We study higher symmetries and anomalies of 4d $mathfrak{so}(2n_c)$ gauge theory with $2n_f$ flavors. We find that they depend on the parity of $n_c$ and $n_f$, the global form of the gauge group, and the discrete theta angle. […]

A pair of warm giant planets near the 2:1 mean motion resonance around the K-dwarf star TOI-2202

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Trifon Trifonov, Rafael Brahm, Nestor Espinoza, Thomas Henning, Andrés Jordán | Summary: TOI-2202 b is a transiting warm Jovian-mass planet with an orbital period of P=11.91 days identified from the Full Frame Images data of five different sectors of the TESS mission. Ten TESS transits of […]

Millicharged dark matter detection with ion traps

Kavli Affiliate: Peter W. Graham | First 5 Authors: Dmitry Budker, Peter W. Graham, Harikrishnan Ramani, Ferdinand Schmidt-Kaler, Christian Smorra | Summary: We propose the use of trapped ions for detection of millicharged dark matter. Millicharged particles will scatter off the ions, giving a signal either in individual events or in the overall heating rate […]

Constraints on scalar field dark matter from co-located Michelson interferometers

Kavli Affiliate: Craig Hogan | First 5 Authors: Lorenzo Aiello, Jonathan W. Richardson, Sander M. Vermeulen, Hartmut Grote, Craig Hogan | Summary: Low-mass (sub-eV) scalar field dark matter may induce apparent oscillations of fundamental constants, resulting in corresponding oscillations of the size and the index of refraction of solids. Laser interferometers are highly sensitive to […]
