Kavli Affiliate: Luis C. Ho | First 5 Authors: Min Du, Luis C. Ho, Hao-Ran Yu, Victor P. Debattista, | Summary: The IllustrisTNG simulations reproduce well the observed scaling relation between specific angular momentum (sAM) $j_{rm s}$ and mass $M_{rm s}$ of galaxies, i.e., the $j_{rm s}$-$M_{rm s}$ relation. This relation develops in disk galaxies […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Min Du, Luis C. Ho, Hao-Ran Yu, Victor P. Debattista, | Summary: The IllustrisTNG simulations reproduce the observed scaling relation between stellar specific angular momentum (sAM) $j_{rm s}$ and mass $M_{rm s}$ of central galaxies. We show that the local $j_{rm s}$-$M_{rm s}$ relation ${rm log} […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Amir Afaq, Zeeshan Ahmed, Noman Haider, Muhammad Imran, | Summary: Federated Learning (FL) provides privacy preservation by allowing the model training at edge devices without the need of sending the data from edge to a centralized server. FL has distributed the implementation of ML. Another variant of […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Wei-Jian Guo, Yan-Rong Li, Zhi-Xiang Zhang, Luis C. Ho, Jian-Min Wan | Summary: We compile a sample of 92 active galactic nuclei (AGNs) at z<0.75 with $gri$ photometric light curves from the archival data of the Zwicky Transient Facility and measure the accretion disk sizes via […]
Kavli Affiliate: Sara Seager | First 5 Authors: Zifan Lin, Sara Seager, Sukrit Ranjan, Thea Kozakis, Lisa Kaltenegger | Summary: Following the discovery of the first exoplanet candidate transiting a white dwarf (WD), a "white dwarf opportunity" for characterizing the atmospheres of terrestrial exoplanets around WDs is emerging. Large planet-to-star size ratios and hence large […]
Kavli Affiliate: Avi Shporer | First 5 Authors: Ian Wong, Avi Shporer, Shreyas Vissapragada, Michael Greklek-McKeon, Heather A. Knutson | Summary: After observing WASP-12 in the second year of the primary mission, the Transiting Exoplanet Survey Satellite (TESS) revisited the system in late 2021 during its extended mission. In this paper, we incorporate the new […]
Kavli Affiliate: Sara Seager | First 5 Authors: Sukrit Ranjan, Sara Seager, Zhuchang Zhan, Daniel D. B. Koll, William Bains | Summary: About 2.5 billion years ago, microbes learned to harness plentiful Solar energy to reduce CO$_2$ with H$_2$O, extracting energy and producing O$_2$ as waste. O$_2$ production from this metabolic process was so vigorous […]
Kavli Affiliate: Jia Liu | First 5 Authors: Max E. Lee, Tianhuan Lu, Zoltán Haiman, Jia Liu, Ken Osato | Summary: Next-generation weak lensing (WL) surveys, such as by the Vera Rubin Observatory’s LSST, the $textit{Roman}$ Space Telescope, and the $textit{Euclid}$ space mission, will supply vast amounts of data probing small, highly nonlinear scales. Extracting […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Sudipta Sikder, Rennan Barkana, Itamar Reis, Anastasia Fialkov, | Summary: The cosmic 21-cm line of hydrogen is expected to be measured in detail by the next generation of radio telescopes. The enormous dataset from future 21-cm surveys will revolutionize our understanding of early cosmic times. We present […]
Kavli Affiliate: Jing Wang | First 5 Authors: Devansh Bisla, Jing Wang, Anna Choromanska, , | Summary: In this paper, we study the sharpness of a deep learning (DL) loss landscape around local minima in order to reveal systematic mechanisms underlying the generalization abilities of DL models. Our analysis is performed across varying network and […]
