The Unhurried Universe: A Continued Search for Long Term Variability in ASAS-SN

Kavli Affiliate: Subo Dong | First 5 Authors: Sydney Petz, Sydney Petz, , , | Summary: We search a sample of 5,685,060 isolated sources in the All Sky Automated Survey for SuperNovae (ASAS-SN) with 14.5<g<15 mag for slowly varying sources with brightness changes larger than ~0.03 mag/year over 10 years. We find 426 slowly-varying systems. […]

4KAgent: Agentic Any Image to 4K Super-Resolution

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Yushen Zuo, Yushen Zuo, , , | Summary: We present 4KAgent, a unified agentic super-resolution generalist system designed to universally upscale any image to 4K resolution (and even higher, if applied iteratively). Our system can transform images from extremely low resolutions with severe degradations, for example, […]

The Nineteenth Data Release of the Sloan Digital Sky Survey

Kavli Affiliate: Alexander P. Ji | First 5 Authors: SDSS Collaboration, SDSS Collaboration, , , | Summary: Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial objects to constrain the physical processes that […]

Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy

Kavli Affiliate: Claudio Ricci | First 5 Authors: Juna A. Kollmeier, Juna A. Kollmeier, , , | Summary: The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the sky with multi-object spectroscopy (MOS) at telescopes in both hemispheres (the 2.5-m Sloan Foundation […]

The Distribution of Atomic Hydrogen in the Host Galaxies of FRBs

Kavli Affiliate: Jing Wang | First 5 Authors: Hugh Roxburgh, Hugh Roxburgh, , , | Summary: We probe the atomic hydrogen (HI) emission from the host galaxies of fast radio bursts (FRBs) to investigate the emerging trend of disturbance and asymmetry in the population. Quadrupling the sample size, we detect 13 of 14 new hosts […]

Gap reopening as signature of coupling between Majorana zero modes in Sn-(Bi,Sb)2(Te,S)3-based Josephson trijunctions

Kavli Affiliate: Xiang Zhang | First 5 Authors: Duolin Wang, Duolin Wang, , , | Summary: In the past two decades, enormous efforts have been made to search for possible platforms and schemes to implement topological quantum computation (TQC). In exploring the Fu-Kane scheme of TQC based on Josephson trijunctions constructed on topological insulators, the […]

Intergalactic Medium Tomography with the Sunburst Arc

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michelle A. Berg, Michelle A. Berg, , , | Summary: Gravitational lensing has transformed the field of gas tomography in the intergalactic medium (IGM) and circumgalactic medium (CGM). Here we use the brightest lensed galaxy identified to date, the Sunburst Arc ($z$$approx$2.37), to constrain the physical […]

Wakes from Companion Interactions in Type Ia Supernovae Nebular Emission Line Profiles

Kavli Affiliate: Lars Bildsten | First 5 Authors: Kathlynn Simotas, Kathlynn Simotas, , , | Summary: Thermonuclear supernovae (SNe) are the result of the nuclear transformation of carbon/oxygen (C/O) white dwarfs (WDs) to the radioactive element $^56mathrmNi$ and intermediate mass elements (IMEs) like Ca, Ar, etc. Most progenitor scenarios involve a companion star which donates […]

Broad-band Spectral Modeling of Prompt Emission from Gamma-Ray Bursts Observed by the Transiting Exoplanet Survey Satellite

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Rahul Jayaraman, Rahul Jayaraman, , , | Summary: Optical observations of gamma-ray bursts (GRBs) contemporaneous with their prompt high-energy emission are rare, but they can provide insights into the physical processes underlying these explosive events. The Transiting Exoplanet Survey Satellite’s (TESS) large field of view and continuous […]
