LensNet: Enhancing Real-time Microlensing Event Discovery with Recurrent Neural Networks in the Korea Microlensing Telescope Network

Posted by dbos MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Javier Viaña, Kyu-Ha Hwang, Zoë de Beurs, Jennifer C. Yee, Andrew Vanderburg | Summary: Traditional microlensing event vetting methods require highly trained human experts, and the process is both complex and time-consuming. This reliance on manual inspection often leads to inefficiencies and constrains the ability to scale […]

An Exceptionally Powerful, Radiatively Driven Ultrafast Outflow in the Rapidly Accreting AGN REJ1034+396

Posted by dbos Stanford

Kavli Affiliate: Steven Allen | First 5 Authors: Chloe Taylor, Daniel Wilkins, Steven Allen, , | Summary: We report the analysis of ~1Ms of XMM-Newton observations of the rapidly accreting active galactic nucleus REJ1034+396. The 0.3-9 keV EPIC-pn spectra are well described by a model consisting of steep continuum emission from the corona accompanied by […]

Prediction-Assisted Online Distributed Deep Learning Workload Scheduling in GPU Clusters

Posted by dbos Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Ziyue Luo, Jia Liu, Myungjin Lee, Ness B. Shroff, | Summary: The recent explosive growth of deep learning (DL) models has necessitated a compelling need for efficient job scheduling for distributed deep learning training with mixed parallelisms (DDLwMP) in GPU clusters. This paper proposes an adaptive shortest-remaining-processing-time-first […]

A Disintegrating Rocky Planet with Prominent Comet-like Tails Around a Bright Star

Posted by dbos MIT

Kavli Affiliate: Avi Shporer | First 5 Authors: Marc Hon, Saul Rappaport, Avi Shporer, Andrew Vanderburg, Karen A. Collins | Summary: We report the discovery of BD+05$,$4868$,$Ab, a transiting exoplanet orbiting a bright ($V=10.16$) K-dwarf (TIC 466376085) with a period of 1.27 days. Observations from NASA’s Transiting Exoplanet Survey Satellite (TESS) reveal variable transit depths […]

The impact of the redshift-dependent selection effect of halos on the redshift-space power spectrum

Posted by dbos Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Kanmi Nose, Masahiro Takada, Ryo Terasawa, , | Summary: In a wide-area spectroscopic survey of galaxies, it is nearly impossible to obtain a homogeneous sample of galaxies with respect to galaxy properties such as stellar mass and host halo mass across a range of redshifts. Despite the […]
