Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Atsushi Naruko, Ryo Saito, Atsushi Taruya, Daisuke Yamauchi | Summary: We develop a systematic and unified approach to estimate all possible secondary (i.e. non-primordial) nonlinear effects to the cosmic microwave background (CMB) polarization, named curve-of-sight integration approach. In this approach, the Boltzmann equation for polarized […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward W. Kolb, Andrew J. Long, Evan McDonough, , | Summary: We extend the swampland from effective field theories (EFTs) inconsistent with quantum gravity to EFTs inconsistent with quantum supergravity. This enlarges the swampland to include EFTs that become inconsistent when the gravitino is quantized. We […]
Kavli Affiliate: Jacqueline N. Hewitt | First 5 Authors: Jianrong Tan, Adrian Liu, Nicholas S. Kern, Zara Abdurashidova, James E. Aguirre | Summary: Precise measurements of the 21 cm power spectrum are crucial for understanding the physical processes of hydrogen reionization. Currently, this probe is being pursued by low-frequency radio interferometer arrays. As these experiments […]
Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, , , , | Summary: In this note we consider Coulomb-branch chiral primary correlation functions in ${cal N} = 2$ superconformal QCD with gauge group $SU(2)$, in the limit of large R-charge ${cal J} = 2n$ for the chiral primary operators $[{cal O}(x)]^ n$ with […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Dongmin Gang, Sungjoon Kim, Kimyeong Lee, Myungbo Shim, Masahito Yamazaki | Summary: We propose a novel procedure of assigning a pair of non-unitary topological quantum field theories (TQFTs), TFT$_pm [mathcal{T}_{rm rank ;0}]$, to a (2+1)D interacting $mathcal{N}=4$ superconformal field theory (SCFT) $mathcal{T}_{rm rank ;0}$ of rank 0, […]
Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, , , , | Summary: This paper investigates whether changes to late time physics can resolve the `Hubble tension’. It is argued that many of the claims in the literature favouring such solutions are caused by a misunderstanding of how distance ladder measurements actually work […]
Kavli Affiliate: Albert Stebbins | First 5 Authors: Jack Burns, Gregg Hallinan, Tzu-Ching Chang, Marin Anderson, Judd Bowman | Summary: An array of low-frequency dipole antennas on the lunar farside surface will probe a unique, unexplored epoch in the early Universe called the Dark Ages. It begins at Recombination when neutral hydrogen atoms formed, first […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration, R. Abbott, T. D. Abbott | Summary: We report results from searches for anisotropic stochastic gravitational-wave backgrounds using data from the first three observing runs of the Advanced LIGO and Advanced Virgo detectors. For the first time, […]
Kavli Affiliate: Laura Schaefer | First 5 Authors: Edwin S. Kite, Laura Schaefer, , , | Summary: Data suggest that most rocky exoplanets with orbital period $p$ $<$ 100 d ("hot" rocky exoplanets) formed as gas-rich sub-Neptunes that subsequently lost most of their envelopes, but whether these rocky exoplanets still have atmospheres is unknown. We […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Alex Drlica-Wagner, Edgar Marrufo Villalpando, Judah O’Neil, Juan Estrada, Stephen Holland | Summary: We characterize the response of a novel 250 $mu$m thick, fully-depleted Skipper Charged-Coupled Device (CCD) to visible/near-infrared light with a focus on potential applications for astronomical observations. We achieve stable, single-electron resolution with readout […]
