Boson stars in massless and massive scalar-tensor gravity

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Tamara Evstafyeva, Roxana Rosca-Mead, Ulrich Sperhake, Bernd Brugmann, | Summary: We study phenomenological features and stability of boson stars in massless and massive scalar-tensor theory of gravity with Damour-Esposito-Farese coupling. This coupling between the tensor and scalar sectors of the theory leads to a phenomenon called spontaneous […]

How Nested Bars Enhance, Modulate, and are Destroyed by Gas Inflows

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhi Li, Min Du, Victor P. Debattista, Juntai Shen, Hui Li | Summary: Gas flows in the presence of two independently-rotating nested bars remain not fully understood, which is likely to play an important role in fueling the central black hole. We use high-resolution hydrodynamical simulations with […]

Robust cosmological inference from non-linear scales with k-th nearest neighbor statistics

Kavli Affiliate: Tom Abel | First 5 Authors: Sihan Yuan, Tom Abel, Risa H. Wechsler, , | Summary: We present the methodology for deriving accurate and reliable cosmological constraints from non-linear scales (<50Mpc/h) with k-th nearest neighbor (kNN) statistics. We detail our methods for choosing robust minimum scale cuts and validating galaxy-halo connection models. Using […]

Exploring chemical enrichment of the intracluster medium with the Line Emission Mapper

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: François Mernier, Yuanyuan Su, Maxim Markevitch, Congyao Zhang, Aurora Simionescu | Summary: Synthesized in the cores of stars and supernovae, most metals disperse over cosmic scales and are ultimately deposited well outside the gravitational potential of their host galaxies. Since their presence is well visible through their […]

The Supersonic Project: Lighting up the faint end of the JWST UV luminosity function

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Claire E. Williams, William Lake, Smadar Naoz, Blakesley Burkhart, Tommaso Treu | Summary: The James Webb Space Telescope (JWST) is capable of probing extremely early eras of our Universe when the supersonic relative motions between dark matter and baryonic overdensities modulate structure formation ($z>sim 10$). We study […]
