Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Junna Sugiyama, Tomoki Terasaki, Kana Sakaguri, Bryce Bixler, Yuki Sakurai | Summary: The Simons Observatory (SO) experiment is a cosmic microwave background (CMB) experiment located in the Atacama Desert, Chile. The SO’ s small aperture telescopes (SATs) consist of three telescopes designed for precise CMB polarimetry at […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Ryan Mckinven, Mohit Bhardwaj, Tarraneh Eftekhari, Charles D. Kilpatrick, Aida Kirichenko | Summary: Fast radio bursts (FRBs) last for milliseconds and arrive at Earth from cosmological distances. While their origin(s) and emission mechanism(s) are presently unknown, their signals bear similarities with the much less luminous radio […]
Kavli Affiliate: C. M. Ignarra | First 5 Authors: J. Aalbers, D. S. Akerib, A. K. Al Musalhi, C. S. Amarasinghe, A. Ames | Summary: Searches for dark matter with liquid xenon time projection chamber experiments have traditionally focused on the region of the parameter space that is characteristic of weakly interacting massive particles, ranging […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Martin Millon, Kevin Michalewicz, Frédéric Dux, Frédéric Courbin, Philip J. Marshall | Summary: We present STARRED, a Point Spread Function (PSF) reconstruction, two-channel deconvolution, and light curve extraction method designed for high-precision photometric measurements in imaging time series. An improved resolution of the data is targeted […]

Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Riccardo Arcodia, Erin Kara, Giovanni Miniutti, Margherita Giustini | Summary: Quasi-Periodic Eruptions (QPEs) are luminous X-ray outbursts recurring on hour timescales, observed from the nuclei of a growing handful of nearby low-mass galaxies. Their physical origin is still debated, and usually modeled as (a) accretion […]

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Sean Heston, Shunsaku Horiuchi, Satoshi Shirai, , | Summary: We constrain the neutrino-dark matter cross section using properties of the dark matter density profiles of Milky Way dwarf spheroidal galaxies. The constraint arises from core-collapse supernova neutrinos scattering on dark matter as a form of energy injection, […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Josh Borrow, Yongao Hu, Evan Erickson | Summary: We investigate galaxy sizes at redshift $zgtrsim 6$ with the cosmological radiation-magneto-hydrodynamic simulation suite THESAN(-HR). These simulations simultaneously capture the reionization of the large-scale intergalactic medium and resolved galaxy properties. The intrinsic size ($r^{ast}_{1/2}$) of […]
