Recent Advances in Metasurface Design and Quantum Optics Applications with Machine Learning, Physics-Informed Neural Networks, and Topology Optimization Methods

Posted by klaurent July 18, 2023Delft

Kavli Affiliate: Simon Groblacher | First 5 Authors: Wenye Ji, Jin Chang2, He-Xiu Xu, Jian Rong Gao, Simon Gröblacher | Summary: As a two-dimensional planar material with low depth profile, a metasurface can generate non-classical phase distributions for the transmitted and reflected electromagnetic waves at its interface. Thus, it offers more flexibility to control the […]

A Large and Variable Leading Tail of Helium in a Hot Saturn Undergoing Runaway Inflation

Posted by klaurent July 18, 2023MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Michael Gully-Santiago, Caroline V. Morley, Jessica Luna, Morgan MacLeod, Antonija Oklopčić | Summary: Atmospheric escape shapes the fate of exoplanets, with statistical evidence for transformative mass loss imprinted across the mass-radius-insolation distribution. Here we present transit spectroscopy of the highly irradiated, low-gravity, inflated hot Saturn HAT-P-67 b. […]

Simultaneous multi-site editing of individual genomes using retron arrays

Posted by klaurent July 17, 2023July 24, 2023UCSF

Kavli Affiliate: Seth Shipman | Authors: Alejandro Gonzalez-Delgado, Santiago C Lopez, Matias Rojas-Montero, Chloe B Fishman and Seth L Shipman | Summary: Our understanding of genomics is limited by the scale of our genomic technologies. While libraries of genomic manipulations scaffolded on CRISPR gRNAs have been transformative, these existing approaches are typically multiplexed across genomes. […]

Red Supergiant Candidates for Multimessenger Monitoring of the Next Galactic Supernova

Posted by klaurent July 17, 2023Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Sarah Healy, Shunsaku Horiuchi, Marta Colomer Molla, Dan Milisavljevic, Jeff Tseng | Summary: We compile a catalog of 598 highly probable and 79 likely red supergiants (RSGs) of the Milky Way, which represents the largest list of Galactic RSG candidates to date. We matched distances measured by […]

JADES: deep spectroscopy of a low-mass galaxy at redshift 2.3 quenched by environment

Posted by klaurent July 17, 2023Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Lester Sandles, Francesco D’Eugenio, Jakob M. Helton, Roberto Maiolino, Kevin Hainline | Summary: We report the discovery of a quiescent galaxy at $z=2.34$ with a stellar mass of only $M_star = 9.5^{+1.8}_{-1.2} times 10^{8} mathrm{M}_odot$, based on deep JWST/NIRSpec spectroscopy. This is the least massive quiescent galaxy […]

SIMPLE: Simple Intensity Map Producer for Line Emission

Posted by klaurent July 17, 2023Tokyo

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Maja Lujan Niemeyer, José Luis Bernal, Eiichiro Komatsu, , | Summary: We present the Simple Intensity Map Producer for Line Emission (SIMPLE), a public code to quickly simulate mock line-intensity maps, and an analytical framework to model intensity maps including observational effects. SIMPLE can be applied to […]

Changing-look Active Galactic Nuclei from the Dark Energy Spectroscopic Instrument. I.Sample from the Early Data

Posted by klaurent July 17, 2023Peking

Kavli Affiliate: Linhua Jiang | First 5 Authors: Wei-Jian Guo, Hu Zou, Victoria Anne Fawcett, Rebecca Canning, Stephanie Juneau | Summary: Changing-look Active Galactic Nuclei (CL AGN) can be generally confirmed by the emergence (turn-on) or disappearance (turn-off) of broad emission lines, associated with a transient timescale (about $100sim5000$ days) that is much shorter than […]

Intercellular communication atlas reveals Oprm1 as a neuroprotective factor for retinal ganglion cells

Posted by klaurent July 17, 2023September 26, 2023Hopkins

Kavli Affiliate: Seth Blackshaw | Authors: Cheng Qian, Ying Xin, Cheng Qi, Hui Wang, Bryan C. Dong, Donald Zack, Seth Blackshaw, Samer Hattar, Feng-Quan Zhou and Jiang Qian | Summary: The progressive death of mature neurons often results in neurodegenerative diseases. While the previous studies have mostly focused on identifying intrinsic mechanisms controlling neuronal survival, […]

Growth of Seed Black Holes in Galactic Nuclei

Posted by klaurent July 16, 2023Peking

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Rainer Spurzem, Francesco Rizzuto, Manuel Arca Sedda, Albrecht Kamlah, Peter Berczik | Summary: The evolution of dense star clusters is followed by direct high-accuracy N-body simulation. The problem is to first order a gravitational N-body problem, but stars evolve due to astrophysics and the more massive ones […]

Revise thermal winds of remnant neutron stars in gamma-ray bursts

Posted by klaurent July 16, 2023Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Shuang Du, Tingting Lin, Shujin Hou, Renxin Xu, | Summary: It seems that the wealth of information revealed by the multi-messenger observations of the binary neutron star (NS) merger event, GW170817/GRB 170817A/kilonova AT2017gfo, places irreconcilable constraints to models of the prompt emission of this gamma-ray burst (GRB).
