Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Kazumi Kashiyama, Eli Visbal, Zoltan Haiman, | Summary: The successive discoveries of binary merger events by Advanced LIGO-Virgo have been revealing the statistical properties of binary black hole (BBH) populations. A stochastic gravitational wave background (GWB) is a useful tool to probe the cosmological evolution […]
Kavli Affiliate: Christopher J. Burke | First 5 Authors: Natalia M. Guerrero, S. Seager, Chelsea X. Huang, Andrew Vanderburg, Aylin Garcia Soto | Summary: We present 2,241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its two-year prime mission. We list these candidates in the TESS Objects of Interest (TOI) […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, , , , | Summary: Spacetime theories obtained from perturbative string theory constructions are automatically free of perturbative anomalies, but it is not settled whether they are always free of global anomalies. Here we discuss a possible $mathbb{Z}_{24}$-valued pure gravitational anomaly of heterotic compactifications down […]
Kavli Affiliate: Erin Kara | First 5 Authors: Ann Zabludoff, Iair Arcavi, Stephanie La Massa, Hagai B. Perets, Benny Trakhtenbrot | Summary: Recent claimed detections of tidal disruption events (TDEs) in multi-wavelength data have opened potential new windows into the evolution and properties of otherwise dormant supermassive black holes (SMBHs) in the centres of galaxies. […]
Kavli Affiliate: Michael Gladders | First 5 Authors: Peter R. Williams, Tommaso Treu, Håkon Dahle, Stefano Valenti, Louis Abramson | Summary: We present CIV BLR modeling results for the multiply imaged $z=2.805$ quasar SDSS J2222+2745. Using data covering a 5.3 year baseline after accounting for gravitational time delays, we find models that can reproduce the […]

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 […]
