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

Posted by klaurent MIT

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 klaurent MIT

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 klaurent MIT

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 […]

Mitochondria morphology governs ATP production rate

Posted by klaurent UCSD / Salk

Kavli Affiliate: Terrence Sejnowski | Authors: Guadalupe C. Garcia, Kavya Gupta, Thomas M. Bartol, Jr., Terrence J. Sejnowski and Padmini Rangamani | Summary: Life is based on energy conversion. In particular, in the nervous system significant amounts of energy are needed to maintain synaptic transmission and homeostasis. To a large extent, neurons depend on oxidative […]

A unified framework to identify demographic buffering in natural populations

Posted by klaurent UCSD / Salk

Kavli Affiliate: Gabriel Silva | Authors: Gabriel Silva Santos, Samuel J L Gascoigne, Andre Tavares Correia Dias, Maja Kajin and Rob Salguero-Gomez | Summary: The Demographic Buffering Hypothesis (DBH) predicts that natural selection reduces the temporal fluctuations in demographic processes (such as survival, development, and reproduction), due to their negative impacts on population dynamics. However, […]

Cognitive rehabilitation can improve brain injury-induced deficits in behavioral flexibility and impulsivity linked to impaired reward-feedback activity.

Posted by klaurent UCSD / Salk

Kavli Affiliate: Dhakshin Ramanathan | Authors: Miranda Francoeur Koloski, Christopher M O’Hearn, Michelle Frankot, Lauren P Giesler, Dhakshin S Ramanathan and Cole Vonder Haar | Summary: Traumatic brain injury (TBI) affects a large population, resulting in severe cognitive impairments. Although cognitive rehabilitation is an accepted treatment for some deficits, studies in patients are limited in […]
