Kavli Affiliate: David N. Spergel | First 5 Authors: Daniel A. Yahalomi, Ruth Angus, David N. Spergel, Daniel Foreman-Mackey, | Summary: Earth-mass exoplanets on year-long orbits and cool gas giants (CGG) on decade-long orbits lie at the edge of current detection limits. The Terra Hunting Experiment (THE) will take nightly radial velocity (RV) observations on […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Sean Heston, Emily Kehoe, Yudai Suwa, Shunsaku Horiuchi, | Summary: Neutrinos allow the probing of stellar interiors during core collapse, helping to understand the different stages and processes in the collapse. To date, supernova neutrinos have only been detected from a single event, SN1987A. Most studies from […]
Kavli Affiliate: Alexey Bondal | First 5 Authors: Agnieszka Bodzenta, Alexey Bondal, , , | Summary: We define a normal surface $X$ to be codim-2-saturated if any open embedding of $X$ into a normal surface with the complement of codimension 2 is an isomorphism. We show that any normal surface $X$ allows a codim-2-saturated model […]

Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Xingyao Chen, Shuailiang Ge, Jia Liu, Yan Luo | Summary: Ultralight dark photons and axions are well-motivated hypothetical dark matter candidates. Both dark photon dark matter and axion dark matter can resonantly convert into electromagnetic waves in the solar corona when their mass is equal […]
Kavli Affiliate: John Silverman | First 5 Authors: Johan Comparat, Wentao Luo, Andrea Merloni, Surhud More, Mara Salvato | Summary: Which galaxies in the general population turn into active galactic nuclei (AGNs) is a keystone of galaxy formation and evolution. Thanks to SRG/eROSITA’s contiguous 140 square degree pilot survey field, we constructed a large, complete, […]
