Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Claudius Krause, Zhen Liu, Yikun Wang, | Summary: Electroweak symmetry non-restoration up to high temperatures well above the electroweak scale offers new alternatives for baryogenesis. We propose a new approach for electroweak symmetry non-restoration via an inert Higgs sector that couples to the Standard Model […]
Kavli Affiliate: Brian Nord | First 5 Authors: Priyamvada Natarajan, Kwok Sun Tang, Robert McGibbon, Sadegh Khochfar, Brian Nord | Summary: We present QuasarNet, a novel research platform for the data-driven investigation of super-massive black hole (SMBH) populations. While SMBH data sets — observations and simulations — have grown rapidly in complexity and abundance, our […]
Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Vadim A. Semenov, Andrey V. Kravtsov, Nickolay Y. Gnedin, , | Summary: The spatial decorrelation of dense molecular gas and young stars observed on $lesssim 1$ kiloparsec scales in nearby galaxies indicates rapid dispersal of star-forming regions by stellar feedback. We explore the sensitivity of this […]
Kavli Affiliate: Michael Gladders | First 5 Authors: Brian Hayden, David Rubin, Kyle Boone, Greg Aldering, Jakob Nordin | Summary: The See Change survey was designed to make $z>1$ cosmological measurements by efficiently discovering high-redshift Type Ia supernovae (SNe Ia) and improving cluster mass measurements through weak lensing. This survey observed twelve galaxy clusters with […]
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: 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: 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: Andrey Kravtsov | First 5 Authors: Congyao Zhang, Irina Zhuravleva, Andrey Kravtsov, Eugene Churazov, | Summary: A self-similar spherical collapse model predicts a dark matter (DM) splashback and accretion shock in the outskirts of galaxy clusters while misses a key ingredient of structure formation – processes associated with mergers. To fill this gap, […]
Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Jia Liu, Navin McGinnis, Carlos E. M. Wagner, Xiao-Ping Wang, | Summary: We report on an interesting realization of the QCD axion, with mass in the range $mathcal{O}(10)$ MeV. It has previously been shown that although this scenario is stringently constrained from multiple sources, the […]
