Probing extreme black-hole outflows on short timescales via high spectral-resolution X-ray imagers

Posted by dbos MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Ciro Pinto, James F. Steiner, Arash Bodaghee, Priyanka Chakraborty, Malgosia Sobolewska | Summary: We investigate outflows and the physics of super-Eddington versus sub-Eddington regimes in black hole systems. Our focus is on prospective science using next-generation high-resolution soft X-ray instruments. We highlight the properties of black hole […]

A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST

Posted by dbos MIT

Kavli Affiliate: Sara Seager | First 5 Authors: TRAPPIST-1 JWST Community Initiative, :, Julien de Wit, René Doyon, Benjamin V. Rackham | Summary: Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominent is the M8.5V star TRAPPIST-1 and its […]

Linear magneto-conductivity as a DC probe of time-reversal symmetry breaking

Posted by dbos Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Veronika Sunko, Chunxiao Liu, Marc Vila, Ilyoun Na, Yuchen Tang | Summary: Several optical experiments have shown that in magnetic materials the principal axes of response tensors can rotate in a magnetic field. Here we offer a microscopic explanation of this effect, and propose a closely […]

Constraining exotic dark matter models with the dark ages 21-cm signal

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Rajesh Mondal, Rennan Barkana, Anastasia Fialkov, , | Summary: The dark ages 21-cm signal is a powerful tool for precision cosmology and probing new physics. We study two non-standard models: an excess radio background (ERB) model (possibly generated by dark matter decay) and the millicharged dark matter […]

Constraining exotic dark matter models with the dark ages 21-cm signal

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Rajesh Mondal, Rennan Barkana, Anastasia Fialkov, , | Summary: The 21-cm signal from the dark ages is a powerful tool for fundamental cosmology and for probing new physics. While it can be used for precision measurements within standard cosmology, here we study two non-standard models: an excess […]

An Unconditionally Stable Iterative Decoupled Algorithm for Multiple-Network Poroelasticity Model

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Meng Lei, Mingchao Cai, Feng Wang, , | Summary: In this work, we introduce an iterative decoupled algorithm designed for addressing the quasi-static multiple-network poroelasticity problem. This problem pertains to the simultaneous modeling of fluid flow and deformations within an elastic porous medium permeated by multiple fluid […]

Direct measurements of cosmic rays and their possible interpretations

Posted by dbos Stanford

Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Igor V. Moskalenko, , , , | Summary: The last two decades have brought spectacular advances in astrophysics of cosmic rays (CRs) and space- and ground-based astronomy. Launches of missions that employ forefront detector technologies enabled measurements with large effective areas, wide fields of view, and […]
