Endothelial type I interferon signaling modulates the vascular response to ischemic brain injury Kavli Affiliate: Reza Abbasi Asl | Authors: Rahul Biswas, Hasika Wickrama Senevirathne, Yujing Wang, Jiang Zhang, Somabha Mukherjee and Reza Abbasi-Asl | Summary: How the cortex organizes directed functional interactions among individual neurons and how this microscale circuitry maps onto cell types […]
Kavli Affiliate: V. S. Ramachandran | Authors: Simran Sharma, Vijayan Ramachandran, Sneha Sudha Komath, Rohini Muthuswami and Samudrala Gourinath | Summary: Epigenetic regulation of chromatin dynamics via histone acetylation is one of several mechanisms by which eukaryotes regulate gene expression, DNA replication and repair, and maintain genome stability. This function is performed by histone […]
Kavli Affiliate: Eiichiro Komatsu | Summary:The cosmic web preserves a record of the physics that shaped the universe in its earliest moments, the period of exponential expansion known as cosmic inflation. However, if inflation involves significant nonlinear interactions, there are no direct theoretical predictions for the resulting cosmic web. We present the first simulation of […]
Kavli Affiliate: Adam S. Charles | Authors: Ha Yun Anna Yoon, Umaima Afifa, Génesis Ferrer-Imbert, Adam S Charles and Na Ji | Summary: Two-photon calcium imaging is a standard tool for measuring neuronal population activity in vivo, yet how axial resolution, sensor expression strategy, and analysis pipeline jointly affect data accuracy remains poorly characterized. Here, […]
Kavli Affiliate: Linhua Jiang | Summary:Single-epoch (SE) black hole mass estimators based on rest-frame ultraviolet or optical broad lines can be limited by dust attenuation or wavelength coverage. We calibrate estimators based on broad Paschen P$α$ and P$β$ directly against reverberation mapping (RM) masses. We obtained LBT/LUCI near-infrared spectra of 27 SDSS-RM quasars and combined […]
Kavli Affiliate: Linhua Jiang | Summary:Changing-look (CL) AGNs trace rapid changes in nuclear activity, but their connection to host galaxy properties remains unclear. We present a study of the host galaxies of 105 CL AGNs previously selected by comparing DESI and SDSS data. We apply a two-epoch spectrophotometric decomposition to the DESI and SDSS spectra […]
Kavli Affiliate: Linhua Jiang | Summary:Previous works of low-redshift quasar host galaxies have focused on compact quasars and found that their host galaxies are mainly star-forming galaxies. Here we present a study of host galaxies for quasars with extended morphologies in ground-based optical images. We select a sample of more than 1000 type 1 quasars […]
Kavli Affiliate: Roberto Maiolino | Summary:Little Red Dots (LRDs) are compact active galactic nuclei (AGN) with unusual spectral energy distributions and broad Balmer emission, candidate signposts of rapid black-hole growth. We present VLT/FORS2 optical linear spectropolarimetry of the closest known LRD, SDSS J102530.29+140207.3, at z=0.1. In total light, we detect spatially extended narrow-H$α$ emission, probably […]
Kavli Affiliate: Andrew Vanderburg | Summary:The majority of confirmed exoplanets orbit within 1 au of a main-sequence (MS) star. When their stellar hosts evolve off the MS, many of these planets will be engulfed and destroyed, creating empty "forbidden" zones around the stars as they evolve to their final state as a white dwarf (WD). […]
Kavli Affiliate: Blake Sherwin | Summary:Accurate measurements of Cosmic Microwave Background (CMB) B-mode polarization, a key probe of inflationary physics, are hindered by complex Galactic dust foregrounds. Traditional foreground removal with Internal Linear Combination (ILC) fully preserves the primordial signal but requires multi-frequency data and is limited to two-point statistics. We present a novel way […]
