Precise characterization of nanometer-scale systems using interferometric scattering microscopy and Bayesian analysis

Posted by klaurent July 4, 2023Harvard

Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Xander M. de Wit, Amelia W. Paine, Caroline Martin, Aaron M. Goldfain, Rees F. Garmann | Summary: Interferometric scattering microscopy (iSCAT) can image the dynamics of nanometer-scale systems. The typical approach to analyzing interferometric images involves intensive processing, which discards data and limits the precision of […]

Random Walk on Multiple Networks

Posted by klaurent July 4, 2023Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Dongsheng Luo, Yuchen Bian, Yaowei Yan, Xiong Yu, Jun Huan | Summary: Random Walk is a basic algorithm to explore the structure of networks, which can be used in many tasks, such as local community detection and network embedding. Existing random walk methods are based on single […]

BU Canis Minoris — the Most Compact Known Flat Doubly Eclipsing Quadruple System

Posted by dbos July 4, 2023MIT

Kavli Affiliate: Saul Rappaport | First 5 Authors: Theodor Pribulla, Tamás Borkovits, Rahul Jayaraman, Saul Rappaport, Tibor Mitnyan | Summary: We have found that the 2+2 quadruple star system BU CMi is currently the most compact quadruple system known, with an extremely short outer period of only 121 days. The previous record holder was TIC […]

Performance metrics for the continuous distribution of entanglement in multi-user quantum networks

Posted by dbos July 3, 2023Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Álvaro G. Iñesta, Stephanie Wehner, , , | Summary: Entangled states shared among distant nodes are frequently used in quantum network applications. When quantum resources are abundant, entangled states can be continuously distributed across the network, allowing nodes to consume them whenever necessary. This continuous distribution of […]

X-ray metal line emission from the hot circumgalactic medium: probing the effects of supermassive black hole feedback

Posted by klaurent July 3, 2023MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Nhut Truong, Annalisa Pillepich, Dylan Nelson, Ákos Bogdán, Gerrit Schellenberger | Summary: We derive predictions from state-of-the-art cosmological galaxy simulations for the spatial distribution of the hot circumgalactic medium (CGM, ${rm [0.1-1]R_{200c}}$) through its emission lines in the X-ray soft band ($[0.3-1.3]$ keV). In particular, we compare […]

EIGER IV: The cool 10$^4$K circumgalactic environment of high-$z$ galaxies reveals remarkably efficient IGM enrichment

Posted by dbos July 3, 2023MIT

Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Rongmon Bordoloi, Robert A. Simcoe, Jorryt Matthee, Daichi Kashino, Ruari Mackenzie | Summary: We report new observations of the cool diffuse gas around 29, $2.3<z<6.3$ galaxies, using deep JWST/NIRCam slitless grism spectroscopy around the sightline to the quasar J0100+2802. The galaxies span a stellar mass range […]

Mapping the imprints of stellar and AGN feedback in the circumgalactic medium with X-ray microcalorimeters

Posted by dbos July 3, 2023MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Gerrit Schellenberger, Ákos Bogdán, John A. ZuHone, Benjamin D. Oppenheimer, Nhut Truong | Summary: The Astro2020 Decadal Survey has identified the mapping of the circumgalactic medium (CGM, gaseous plasma around galaxies) as a key objective. We explore the prospects for characterizing the CGM in and around nearby […]
