Amplified J-factors in the Galactic Center for velocity-dependent darkmatter annihilation in FIRE simulations

Posted by klaurent MIT

Kavli Affiliate: Lina Necib | First 5 Authors: Daniel McKeown, James S. Bullock, Francisco J. Mercado, Zachary Hafen, Michael Boylan-Kolchin | Summary: We use FIRE-2 zoom cosmological simulations of Milky Way size galaxy halos to calculate astrophysical J-factors for dark matter annihilation and indirect detection studies. In addition to velocity-independent (s-wave) annihilation cross sections $sigma_v$, […]

Moderate and $L^p$ maximal inequalities for diffusion processes and conformal martingales

Posted by klaurent Peking

Kavli Affiliate: Xian Chen | First 5 Authors: Xian Chen, Yong Chen, Mumien Cheng, Chen Jia, | Summary: The $L^p$ maximal inequalities for martingales are one of the classical results in the theory of stochastic processes. Here we establish the sharp moderate maximal inequalities for one-dimensional diffusion processes, which include the $L^p$ maximal inequalities as […]

Supernova-driven turbulent metal mixing in high redshift galactic disks: metallicity fluctuations in the interstellar medium and its imprints on metal poor stars in the Milky Way

Posted by klaurent Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Anne Noer Kolborg, Davide Martizzi, Enrico Ramirez-Ruiz, Hugo Pfister, Charli Sakari | Summary: The extent to which turbulence mixes gas in the face of recurrent infusions of fresh metals by supernovae (SNe) could help provide important constraints on the local star formation conditions. This includes predictions […]

K2-79b and K2-222b: Mass measurements of two small exoplanets with periods beyond 10 days that overlap with periodic magnetic activity signals

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Chantanelle Nava, Mercedes López-Morales, Annelies Mortier, Li Zeng, Helen A. C. Giles | Summary: We present mass and radius measurements of K2-79b and K2-222b, two transiting exoplanets orbiting active G-type stars. Their respective 10.99d and 15.39d orbital periods fall near periods of signals induced by stellar magnetic […]
