Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Abigail J. Lee, Wendy L. Freedman, Barry F. Madore, In Sung Jang, Kayla A. Owens | Summary: The J-region asymptotic giant branch (JAGB) method is a new standard candle based on the constant luminosities of carbon-rich asymptotic giant branch stars in the J band. The JAGB […]

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Aidan P. Cloonan, Gourav Khullar, Kate A. Napier, Michael D. Gladders, Håkon Dahle | Summary: Wide-separation lensed quasars (WSLQs) are a rare class of strongly lensed quasars, magnified by foreground massive galaxy clusters, with typically large magnifications of the multiple quasar images. They are a relatively […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Andrea Dei, Bob Knighton, Kiarash Naderi, Savdeep Sethi, | Summary: One of the few cases of AdS/CFT where both sides of the duality are under good control relates tensionless $k=1$ strings on AdS$_3$ to a two-dimensional symmetric product CFT. Building on prior observations, we propose an exact […]

Kavli Affiliate: Daniel Holz | First 5 Authors: Hannah Middleton, Christopher P L Berry, Nicolas Arnaud, David Blair, Jacqueline Bondell | Summary: The LIGO-Virgo-KAGRA (LVK) Collaboration has made breakthrough discoveries in gravitational-wave astronomy, a new field of astronomy that provides a different means of observing our Universe. Gravitational-wave discoveries are possible thanks to the work […]

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Melissa K. Ness, J. Trevor Mendel, Sven Buder, Adam Wheeler, Alexander P. Ji | Summary: The element abundances of local group galaxies connect enrichment mechanisms to galactic properties and serve to contextualise the Milky Way’s abundance distributions. Individual stellar spectra in nearby galaxies can be extracted […]
Kavli Affiliate: Brian Nord | First 5 Authors: Sreevani Jarugula, Brian Nord, Abhijith Gandrakota, Aleksandra Ćiprijanović, | Summary: In this work, we present a scalable approach for inferring the dark energy equation-of-state parameter ($w$) from a population of strong gravitational lens images using Simulation-Based Inference (SBI). Strong gravitational lensing offers crucial insights into cosmology, but […]
