The Chemical Composition of Extreme-Velocity Stars

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 […]

Simulations of black hole fueling in isolated and merging galaxies with an explicit, multiphase ISM

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 […]

AI Poincaré 2.0: Machine Learning Conservation Laws from Differential Equations

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 […]

Galactic angular momentum in the IllustrisTNG simulation — I. Connection to morphology, halo spin, and black hole mass

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 […]

Advancing the Landscape of Multimessenger Science in the Next Decade

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 […]

Revisiting Kepler Transiting Systems: Unvetting Planets and Constraining Relationships among Harmonics in Phase Curves

Kavli Affiliate: Avi Shporer | First 5 Authors: Prajwal Niraula, Avi Shporer, Ian Wong, Julien de Wit, | Summary: Space-based photometric missions widely use statistical validation tools for vetting transiting planetary candidates, particularly when other traditional methods of planet confirmation are unviable. In this paper, we refute the planetary nature of three previously validated planets […]
