The THESAN project: Lyman-alpha intensity mapping of cosmic reionization

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | Summary:Line Intensity Mapping (LIM) has garnered attention as a powerful cosmological probe, with next-generation instruments such as SPHEREx preparing to map the evolution of large-scale structure during the Epoch of Reionization (EoR). Lyman-alpha emission in the EoR is strongly shaped by resonant absorption from neutral hydrogen in the diffuse intergalactic […]

An Ancient Brown Dwarf Transiting a Metal-Poor Thick Disk Star

Posted by klaurent Harvard

Kavli Affiliate: David Charbonneau | Summary:We report the discovery of TOI-7019b, the first transiting brown dwarf (BD) known to orbit a star that is part of the Milky Way’s ancient thick disk, as defined chemically ([Fe/H] $= -0.79 pm 0.05$ dex, [$α$/Fe] $= +0.26 pm 0.05$ dex, [M/H] $= -0.59 pm 0.06$ dex) and kinematically […]

Spin Polarization from Circularly Polarized Light Induced Charge Transfer

Posted by klaurent Berkeley

Kavli Affiliate: David T. Limmer | Summary:We show how a spin polarization can be generated through the photo-induced electron transfer of an achiral donor-acceptor complex following chiral light excitation. In particular, we illustrate the basic energetic and symmetry requirements for chirality induced spin selectivity where the chirality emerges from the electronic degrees of freedom following […]

Ruminations Upon the Modeling of X-ray Foregrounds, Backgrounds and Faint Sources

Posted by klaurent Stanford

Kavli Affiliate: Steven Allen | Summary:With the goal of extracting as much information as possible from Chandra and XMM-Newton observations of faint, diffuse sources such as galaxy clusters, as well as those of future X-ray telescopes, we present a strategy for forward modeling all the foreground and background signals present in these data. This work […]

Spectrally-selective dynamic radiative thermoregulation via phase engineering

Posted by klaurent Peking

Kavli Affiliate: Xuebing Wu | Summary:Maintaining comfortable temperatures for buildings, humans, and devices consumes a substantial portion of global energy, underscoring the urgent need for energy-efficient thermoregulation technologies. Dynamic radiative thermal emitters that can switch between passive cooling and heating modes offer a promising solution, but most existing devices exhibit broadband optical responses, resulting in […]
