Mini-Quenching of High-Redshift Galaxies by Bursty Star Formation

Kavli Affiliate: George Efstathiou | First 5 Authors: Tibor Dome, Sandro Tacchella, Anastasia Fialkov, Avishai Dekel, Omri Ginzburg | Summary: The recent observation of a low-mass $z=5.2$ and an intermediate-mass $z=7.3$ (JADES-GS-z7-01-QU) quenched galaxy with JWST / NIRSpec is the first evidence of halted star formation above $zsim 5$. Here we show how bursty star […]

Mini-quenching of $z=4-8$ galaxies by bursty star formation

Kavli Affiliate: George Efstathiou | First 5 Authors: Tibor Dome, Sandro Tacchella, Anastasia Fialkov, Daniel Ceverino, Avishai Dekel | Summary: The recent reported discovery of a low-mass $z=5.2$ and an intermediate-mass $z=7.3$ quenched galaxy with JWST/NIRSpec is the first evidence of halted star formation above $zapprox 5$. Here we show how bursty star formation at […]

The Magnificent Five Images of Supernova Refsdal: Time Delay and Magnification Measurements

Kavli Affiliate: Kaisey Mandel | First 5 Authors: Patrick L. Kelly, Steven Rodney, Tommaso Treu, Simon Birrer, Vivien Bonvin | Summary: In late 2014, four images of Supernova (SN) "Refsdal," the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149 galaxy-cluster field. Following the images’ discovery, […]

Constraints on the Hubble constant from Supernova Refsdal’s reappearance

Kavli Affiliate: Kaisey Mandel | First 5 Authors: Patrick L. Kelly, Steven Rodney, Tommaso Treu, Masamune Oguri, Wenlei Chen | Summary: The gravitationally lensed Supernova Refsdal appeared in multiple images, produced through gravitational lensing by a massive foreground galaxy cluster. After the supernova appeared in 2014, lens models of the galaxy cluster predicted an additional […]

Avoiding methane emission rate underestimates when using the divergence method

Kavli Affiliate: Kaisey Mandel | First 5 Authors: Clayton Roberts, Rutger IJzermans, David Randell, Matthew Jones, Philip Jonathan | Summary: Methane is a powerful greenhouse gas, and a primary target for mitigating climate change in the short-term future due to its relatively short atmospheric lifetime and greater ability to trap heat in Earth’s atmosphere compared […]

JADES: Insights on the low-mass end of the mass–metallicity–star-formation rate relation at $3 < z < 10$ from deep JWST/NIRSpec spectroscopy

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Mirko Curti, Roberto Maiolino, Emma Curtis-Lake, Jacopo Chevallard, Stefano Carniani | Summary: We analyse the gas-phase metallicity properties of a sample of low stellar mass (log M*/M_sun <= 9) galaxies at 3 < z < 10, observed with JWST/NIRSpec as part of the JADES programme in its […]

Cosmological evolution of Witten superconducting string networks

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: I. Yu. Rybak, C. J. A. P. Martins, Patrick Peter, E. P. S. Shellard, | Summary: We consider the evolution of current-carrying cosmic string networks described by the charge-velocity-dependent one scale (CVOS) model beyond the linear equation of state regime, specifically focusing on the Witten […]
