A compact and cost-effective laser-powered speckle visibility spectroscopy (SVS) device for measuring cerebral blood flow

Posted by dbos Caltech

Kavli Affiliate: Changhuei Yang | First 5 Authors: Yu Xi Huang, Simon Mahler, Maya Dickson, Aidin Abedi, Julian M. Tyszka | Summary: In the realm of cerebrovascular monitoring, primary metrics typically include blood pressure, which influences cerebral blood flow (CBF) and is contingent upon vessel radius. Measuring CBF non-invasively poses a persistent challenge, primarily attributed […]

SAGAbg I: A Near-Unity Mass Loading Factor in Low-Mass Galaxies via their Low-Redshift Evolution in Stellar Mass, Oxygen Abundance, and Star Formation Rate

Posted by dbos Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Erin Kado-Fong, Marla Geha, Yao-Yuan Mao, Mithi A. C. de los Reyes, Risa H. Wechsler | Summary: Measuring the relation between star formation and galactic winds is observationally difficult. In this work we make an indirect measurement of the mass loading factor (the ratio between mass […]

AT2019pim: A Luminous Orphan Afterglow from a Moderately Relativistic Outflow

Posted by klaurent MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Daniel A. Perley, Anna Y. Q. Ho, Michael Fausnaugh, Gavin P. Lamb, Mansi M. Kasliwal | Summary: Classical gamma-ray bursts (GRBs) have two distinct emission episodes: prompt emission from ultra-relativistic ejecta and afterglow from shocked circumstellar material. While both components are extremely luminous in known GRBs, a […]

Discovery of two warm mini-Neptunes with contrasting densities orbiting the young K3V star TOI-815

Posted by dbos MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Angelica Psaridi, Hugh Osborn, François Bouchy, Monika Lendl, Léna Parc | Summary: We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal it to be a young star with […]

Photoevaporation from Inner Protoplanetary Disks Confronted with Observations

Posted by Peking

Kavli Affiliate: Lile Wang | First 5 Authors: Yiren Lin, Lile Wang, Min Fang, Ahmad Nemer, Jeremy Goodman | Summary: The decades-long explorations on the dispersal of protoplanetary disks involve many debates about photoevaporation versus magnetized wind launching mechanisms. This letter argues that the observed winds originating from the inner disk ($Rlesssim 0.3$ AU) cannot […]
