QuasarNet: A new research platform for the data-driven investigation of black holes
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 […]

Spatial Decorrelation of Young Stars and Dense Gas as a Probe of the Star Formation-Feedback Cycle in Galaxies
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 […]

The HST See Change Program: I. Survey Design, Pipeline, and Supernova Discoveries
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 […]

Dynamical Modeling of the CIV Broad Line Region of the $z=2.805$ Multiply Imaged Quasar SDSS J2222+2745
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 […]

Four-Spin Terms and the Origin of the Chiral Spin Liquid in Mott Insulators on the Triangular Lattice
Kavli Affiliate: Joel E. Moore | First 5 Authors: Tessa Cookmeyer, Johannes Motruk, Joel E. Moore, , | Summary: At strong repulsion, the triangular-lattice Hubbard model is described by $s=1/2$ spins with nearest-neighbor antiferromagnetic Heisenberg interactions and exhibits conventional 120$^circ$ order. Using the infinite density matrix renormalization group and exact diagonalization, we study the effect […]

Evolution of Splashback Boundaries and Gaseous Outskirts: Insights from Mergers of Self-similar Galaxy Clusters
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, […]

Challenges for a QCD Axion at the 10 MeV Scale
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 […]

Imaging local discharge cascades for correlated electrons in WS2/WSe2 moiré superlattices
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Hongyuan Li, Shaowei Li, Mit H. Naik, Jingxu Xie, Xinyu Li | Summary: Transition metal dichalcogenide (TMD) moir’e heterostructures provide an ideal platform to explore the extended Hubbard model1 where long-range Coulomb interactions play a critical role in determining strongly correlated electron states. This has led […]
