Kavli Affiliate: David A. Principe | First 5 Authors: Joel H. Kastner, David A. Principe, , , | Summary: The past two decades have seen dramatic progress in our knowledge of the population of stars of age $lesssim$150 Myr that lie within $sim$100 pc of the Sun. Most such stars are found in loose kinematic […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Henrique Reggiani, Alexander P. Ji, Kevin C. Schlaufman, Anna Frebel, Lina Necib | Summary: Little is known about the origin of the fastest stars in the Galaxy. Our understanding of the Milky Way and surrounding dwarf galaxies chemical evolution history allows us to use the chemical composition […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aneesh Sivasankaran, Laura Blecha, Paul Torrey, Luke Zoltan Kelley, Aklant Bhowmick | Summary: We study gas inflows onto supermassive black holes using hydrodynamics simulations of isolated galaxies and idealized galaxy mergers with an explicit, multiphase interstellar medium (ISM). Our simulations use the recently developed ISM and stellar […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Ziming Liu, Varun Madhavan, Max Tegmark, , | Summary: We present a machine learning algorithm that discovers conservation laws from differential equations, both numerically (parametrized as neural networks) and symbolically, ensuring their functional independence (a non-linear generalization of linear independence). Our independence module can be viewed as […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vicente Rodriguez-Gomez, Shy Genel, S. Michael Fall, Annalisa Pillepich, Marc Huertas-Company | Summary: We use the TNG100 simulation of the IllustrisTNG project to investigate the stellar specific angular momenta ($j_{ast}$) of $sim$12~000 central galaxies at $z=0$ in a full cosmological context, with stellar masses ($M_{ast}$) ranging from […]
Kavli Affiliate: David Shoemaker | First 5 Authors: Kristi Engel, Tiffany Lewis, Marco Stein Muzio, Tonia M. Venters, Markus Ahlers | Summary: The last decade has brought about a profound transformation in multimessenger science. Ten years ago, facilities had been built or were under construction that would eventually discover the nature of objects in our […]
Kavli Affiliate: Salvatore Vitale | First 5 Authors: Stefan W. Ballmer, Rana Adhikari, Leonardo Badurina, Duncan A. Brown, Swapan Chattopadhyay | Summary: The next generation of gravitational-wave observatories can explore a wide range of fundamental physics phenomena throughout the history of the universe. These phenomena include access to the universe’s binary black hole population throughout […]

Kavli Affiliate: Salvatore Vitale | First 5 Authors: Masha Baryakhtar, Regina Caputo, Djuna Croon, Kerstin Perez, Emanuele Berti | Summary: Exploring dark matter via observations of extreme astrophysical environments — defined here as heavy compact objects such as white dwarfs, neutron stars, and black holes, as well as supernovae and compact object merger events — […]
