TESS Shines Light on the Origin of the Ambiguous Nuclear Transient ASASSN-18el

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Jason T. Hinkle, Christopher S. Kochanek, Benjamin J. Shappee, Patrick J. Vallely, Katie Auchettl | Summary: We analyze high-cadence data from the Transiting Exoplanet Survey Satellite (TESS) of the ambiguous nuclear transient (ANT) ASASSN-18el. The optical changing-look phenomenon in ASASSN-18el has been argued to be due to […]

The Mysterious Affair of the H$_2$ in AU Mic

Kavli Affiliate: Gregory Herczeg | First 5 Authors: Laura Flagg, Christopher Johns-Krull, Kevin France, Gregory Herczeg, Joan Najita | Summary: Molecular hydrogen is the most abundant molecule in the Galaxy and plays important roles for planets, their circumstellar environments, and many of their host stars. We have confirmed the presence of molecular hydrogen in the […]

Nested sampling for physical scientists

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Greg Ashton, Noam Bernstein, Johannes Buchner, Xi Chen, Gábor Csányi | Summary: We review Skilling’s nested sampling (NS) algorithm for Bayesian inference and more broadly multi-dimensional integration. After recapitulating the principles of NS, we survey developments in implementing efficient NS algorithms in practice in high-dimensions, including methods […]

MUSSES2020J: The Earliest Discovery of a Fast Blue Ultraluminous Transient at Redshift 1.063

Kavli Affiliate: Naoki Yasuda | First 5 Authors: Ji-an Jiang, Naoki Yasuda, Keiichi Maeda, Nozomu Tominaga, Mamoru Doi | Summary: In this Letter, we report the discovery of an ultraluminous fast-evolving transient in rest-frame UV wavelengths, MUSSES2020J, soon after its occurrence by using the Hyper Suprime-Cam (HSC) mounted on the 8.2 m Subaru telescope. The […]

Keywords and Instances: A Hierarchical Contrastive Learning Framework Unifying Hybrid Granularities for Text Generation

Kavli Affiliate: Feng Wang | First 5 Authors: Mingzhe Li, XieXiong Lin, Xiuying Chen, Jinxiong Chang, Qishen Zhang | Summary: Contrastive learning has achieved impressive success in generation tasks to militate the "exposure bias" problem and discriminatively exploit the different quality of references. Existing works mostly focus on contrastive learning on the instance-level without discriminating […]

Revisiting the Affleck-Dine mechanism for primordial black hole formation

Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Kentaro Kasai, Masahiro Kawasaki, Kai Murai, , | Summary: We study a primordial black hole (PBH) formation scenario based on the Affleck-Dine (AD) mechanism and investigate two PBH mass regions: $M sim 30 M_odot$ motivated by the LIGO-Virgo observations of the binary black hole mergers and $M […]

Towards a spectrally multiplexed quantum repeater

Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Tanmoy Chakraborty, Antariksha Das, Hedser van Brug, Oriol Pietx-Casas, Peng-Cheng Wang | Summary: Extended quantum networks are based on quantum repeaters that often rely on the distribution of entanglement in an efficient and heralded fashion over multiple network nodes. Many repeater architectures require multiplexed sources of entangled […]

The Robotic Multi-Object Focal Plane System of the Dark Energy Spectroscopic Instrument (DESI)

Kavli Affiliate: Kevin Reil | First 5 Authors: Joseph Harry Silber, Parker Fagrelius, Kevin Fanning, Michael Schubnell, Jessica Nicole Aguilar | Summary: A system of 5,020 robotic fiber positioners was installed in 2019 on the Mayall Telescope, at Kitt Peak National Observatory. The robots automatically re-target their optical fibers every 10 – 20 minutes, each […]

Impartial Selection with Additive Guarantees via Iterated Deletion

Kavli Affiliate: Felix Fischer | First 5 Authors: Javier Cembrano, Felix Fischer, David Hannon, Max Klimm, | Summary: Impartial selection is the selection of an individual from a group based on nominations by other members of the group, in such a way that individuals cannot influence their own chance of selection. For this problem, we […]
