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 […]

Long-Lived Light Mediators from Higgs boson Decay at HL-LHC, FCC-hh and a Proposal of Dedicated LLP Detectors for FCC-hh

Posted by klaurent Tokyo

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Biplob Bhattacherjee, Shigeki Matsumoto, Rhitaja Sengupta, , | Summary: We study the pair production of the long-lived mediator particles from the decay of the SM Higgs boson and their subsequent decay into standard model particles. We compute the projected sensitivity, both model-independently and with a minimal model, […]

VLA Radio Study of a Sample of Nearby X-ray and Optically Bright Early-Type Galaxies

Posted by klaurent Stanford

Kavli Affiliate: Steven W. Allen | First 5 Authors: Romana Grossová, Norbert Werner, Francesco Massaro, Kiran Lakhchaura, Tomáš Plšek | Summary: Many massive early-type galaxies host central radio sources and hot X-ray atmospheres indicating the presence of radio-mechanical active galactic nucleus (AGN) feedback. The duty cycle and detailed physics of the radio-mode AGN feedback is […]
