What Causes The Formation of Disks and End of Bursty Star Formation?

Philip F. Hopkins, Alexander B. Gurvich, Xuejian Shen, Zachary Hafen, Michael Y. Grudic | Summary: [[{“value”:”As they grow, galaxies can transition from irregular/spheroidal with ‘bursty’ star formation histories (SFHs), to disky with smooth SFHs. But even in simulations, the direct physical cause of such transitions remains unclear. We therefore explore this in a large suite […]

Probing the interplay between jets, winds and multi-phase gas in 11 radio-quiet PG Quasars: A uGMRT-VLA study

Kavli Affiliate: Luis C. Ho | First 5 Authors: Silpa S., P. Kharb, Luis C. Ho, C. M. Harrison, | Summary: We present polarization-sensitive images from the Karl G. Jansky Very Large Array (VLA) at 5 GHz of 11 radio-quiet PG quasars. Based on the radio morphology, spectral index and polarization properties from the VLA […]

Novel Conservative Methods for Adaptive Force Softening in Collisionless and Multi-Species N-Body Simulations

Philip F. Hopkins, Ethan O. Nadler, Michael Y. Grudic, Xuejian Shen, Isabel Sands | Summary: [[{“value”:”Modeling self-gravity of collisionless fluids (e.g. ensembles of dark matter, stars, black holes, dust, planetary bodies) in simulations is challenging and requires some force softening. It is often desirable to allow softenings to evolve adaptively, in any high-dynamic range simulation, […]

Effects of the interplay between fermionic interactions and disorders in the nodal-line superconductors

Kavli Affiliate: Jing Wang | First 5 Authors: Wen-Hao Bian, Xiao-Zhuo Chu, Jing Wang, , | Summary: We study the interplay between fermion-fermion interactions and disorder scatterings beneath the superconducting dome of noncentrosymmetric nodal-line superconductors. With the application of renormalization group, several interesting low-energy behaviors are extracted from the coupled equations of all interaction parameters. […]

An Information-State Based Approach to Linear Time Varying System Identification and Control

Kavli Affiliate: Ran Wang | First 5 Authors: Mohamed Naveed Gul Mohamed, Raman Goyal, Suman Chakravorty, Ran Wang, | Summary: This paper considers the problem of system identification for linear time varying systems. We propose a new system realization approach that uses an "information-state" as the state vector, where the "information-state" is composed of a […]

Spectral bounds for exit times on metric measure Dirichlet spaces and applications

Kavli Affiliate: Jing Wang | First 5 Authors: Phanuel Mariano, Jing Wang, , , | Summary: Assuming the heat kernel on a doubling Dirichlet metric measure space has a generalized sub-Gaussian bound, we prove an asymptotically sharp spectral upper bound on the survival probability of the associated diffusion process. As a consequence, we can show […]
