BD-14 3065b (TOI-4987b): from giant planet to brown dwarf: evidence for deuterium burning in old age?

Kavli Affiliate: Avi Shporer | First 5 Authors: Ján Šubjak, David W. Latham, Samuel N. Quinn, Perry Berlind, Michael L. Calkins | Summary: The present study reports the confirmation of BD-14 3065b, a transiting planet/brown dwarf in a triple-star system, with a mass near the deuterium burning boundary. BD-14 3065b has the largest radius observed […]

Spacetime symmetries and and geometric diffusion

Kavli Affiliate: J. S. Villasenor | First 5 Authors: Marc Basquens, Antonio Lasanta, Emanuel Mompó, Valle Varo, Eduardo J. S. Villaseñor | Summary: We examine relativistic diffusion through the frame and observer bundles associated with a Lorentzian manifold $(M,g)$. Our focus is on spacetimes with a non-trivial isometry group, and we detail the conditions required […]

Evolution and distribution of superbubbles in simulated Milky Way-like galaxies

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Chengzhe Li, Hui Li, Wei Cui, Federico Marinacci, Laura V. Sales | Summary: Stellar feedback plays a crucial role in regulating baryon cycles of a galactic ecosystem, and may manifest itself in the formation of superbubbles in the interstellar medium. In this work, we used a set […]

EIGER VI. The Correlation Function, Host Halo Mass and Duty Cycle of Luminous Quasars at $zgtrsim6$

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Anna-Christina Eilers, Ruari Mackenzie, Elia Pizzati, Jorryt Matthee, Joseph F. Hennawi | Summary: We expect luminous ($M_{1450}lesssim-26.5$) high-redshift quasars to trace the highest density peaks in our universe, and therefore to reside in proto-clusters encompassing an abundance of galaxies in close vicinity. Here, we present observations […]

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Anna-Christina Eilers, Ruari Mackenzie, Elia Pizzati, Jorryt Matthee, Joseph F. Hennawi | Summary: We expect luminous ($M_{1450}lesssim-26.5$) high-redshift quasars to trace the highest density peaks in the early universe. Here, we present observations of four $zgtrsim6$ quasar fields using JWST/NIRCam in imaging and widefield slitless spectroscopy […]

QCD at 50: Golden Anniversary, Golden Insights, Golden Opportunities

Kavli Affiliate: Frank Wilczek | First 5 Authors: Frank Wilczek, , , , | Summary: The bulk of this paper centers around the tension between confinement and freedom in QCD. I discuss how it can be understood heuristically as a manifestation of self-adhesive glue and how it fits within the larger contexts of energy-time uncertainty […]
