Kavli Affiliate: Carlos E. M. Wagner | First 5 Authors: Leandro Da Rold, Anibal D. Medina, Subhojit Roy, Carlos E. M. Wagner, | Summary: Although protons are baryons with an overall vanishing lepton number, they possess a non-trivial leptonic content arising from quantum fluctuations which can be described by lepton parton distribution functions (PDFs) of […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Wayne Hu, Qiuyue Liang, Meng-Xiang Lin, Mark Trodden, | Summary: We consider the effects of relaxing the assumption that gravitational waves composing the stochastic gravitational wave background (SGWB) are uncorrelated between frequencies in analyses of the data from Pulsar Timing Arrays (PTAs). While individual monochromatic plane waves […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Yuan-Sen Ting, Alexander P. Ji, , , | Summary: Dwarf galaxy star formation histories are theoretically expected to be bursty, potentially leaving distinct imprints on their chemical evolution. We propose that episodic starbursts with quiescent periods longer than $sim$100 Myr should lead to discontinuous tracks in […]
Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Wendy L. Freedman, Barry F. Madore, In Sung Jang, Taylor J. Hoyt, Abigail J. Lee | Summary: We present the latest results from the Chicago Carnegie Hubble Program (CCHP) to measure the Hubble constant using data from the James Webb Space Telescope (JWST). This program is […]
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 […]
