Rapid dimming followed by a state transition: a study of the highly variable nuclear transient AT 2019avd over 1000+ days

Kavli Affiliate: Ronald Remillard | First 5 Authors: Yanan Wang, Dheeraj R. Pasham, Diego Altamirano, Andres Gurpide, Noel Castro Segura | Summary: The tidal disruption of a star around a supermassive black hole (SMBH) offers a unique opportunity to study accretion onto a SMBH on a human-timescale. We present results from our 1000+ days NICER, […]

The impact of bias row noise to photometric accuracy: case study based on a scientific CMOS detector

Kavli Affiliate: Hu Zhan | First 5 Authors: Li Shao, Hu Zhan, Chao Liu, Haonan Chi, Qiuyan Luo | Summary: We tested a new model of CMOS detector manufactured by the Gpixel Inc, for potential space astronomical application. In laboratory, we obtain some bias images under the typical application environment. In these bias images, clear […]

SENSEI: First Direct-Detection Results on sub-GeV Dark Matter from SENSEI at SNOLAB

Kavli Affiliate: Michael Crisler | Summary:We present the first results from a dark matter search using six Skipper-CCDs in the SENSEI detector operating at SNOLAB. We employ a bias-mitigation technique of hiding approximately 46% of our total data and aggressively mask images to remove backgrounds. Given a total exposure after masking of 100.72 gram-days from […]

Repaint123: Fast and High-quality One Image to 3D Generation with Progressive Controllable 2D Repainting

Kavli Affiliate: Cheng Peng | First 5 Authors: Junwu Zhang, Zhenyu Tang, Yatian Pang, Xinhua Cheng, Peng Jin | Summary: Recent one image to 3D generation methods commonly adopt Score Distillation Sampling (SDS). Despite the impressive results, there are multiple deficiencies including multi-view inconsistency, over-saturated and over-smoothed textures, as well as the slow generation speed. […]

Circuit-motivated generalized affine models characterize stimulus-dependent visual cortical shared variability

Kavli Affiliate: Kenneth Miller | Authors: Ji Xia, Anna Jasper, Adam Kohn and Kenneth D Miller | Summary: Correlated variability in the visual cortex is modulated by stimulus properties. The stimulus dependence of correlated variability impacts stimulus coding and is indicative of circuit structure. An affine model combining a factor proportional to mean stimulus response […]

Euclidean self-dual gravity: Ashtekar variables without gauge fixing

Kavli Affiliate: J. S. Villasenor | Summary:The Gotay-Nester-Hinds method is used in this paper to study the Hamiltonian formulation of the Euclidean self-dual action. This action can be used to arrive at the complex Ashtekar formulation of General Relativity or a real connection formulation for Euclidean General Relativity. The main result of the paper is […]

A degenerate trion liquid in atomic double layers

Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Raghav Chaturvedi, Liguo Ma, Patrick Knuppel, Kenji Watanabe | Summary: Trions are a three-particle bound state of electrons and holes. Experimental realization of a trion liquid in the degenerate quantum limit would open a wide range of phenomena in quantum many-body physics. However, trions […]

Dynamics in Star-forming Cores (DiSCo): Project Overview and the First Look toward the B1 and NGC 1333 Regions in Perseus

Kavli Affiliate: Sarah Church | Summary:The internal velocity structure within dense gaseous cores plays a crucial role in providing the initial conditions for star formation in molecular clouds. However, the kinematic properties of dense gas at core scales (~0.01 – 0.1 pc) has not been extensively characterized because of instrument limitations until the unique capabilities […]
