Unusual Hard X-ray Flares Caught in NICER Monitoring of the Binary Supermassive Black Hole Candidate AT2019cuk/Tick Tock/SDSS J1430+2303

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Megan Masterson, Erin Kara, Dheeraj R. Pasham, Daniel J. D’Orazio, Dominic J. Walton | Summary: The nuclear transient AT2019cuk/Tick Tock/SDSS J1430+2303 has been suggested to harbor a supermassive black hole (SMBH) binary near coalescence. We report results from high-cadence NICER X-ray monitoring with multiple visits per […]

Wet Compaction to a Blue Nugget: a Critical Phase in Galaxy Evolution

Sharon Lapiner, Avishai Dekel, Jonathan Freundlich, Omri Ginzburg, Fangzhou Jiang | Summary: [[{“value”:”We utilize high-resolution cosmological simulations to reveal that high-redshift galaxies tend to undergo a robust `wet compaction’ event when near a `golden’ stellar mass of $sim 10^{10} M_{odot}$. This is a gaseous shrinkage to a compact star-forming phase, a `blue nugget’ (BN), followed […]

Neuronal Transcriptome Disruption, Tau Accumulation and Synapse Loss in Alzheimer’s Knock-in Mice Require Cellular Prion Protein

Kavli Affiliate: Stephen Strittmatter | Authors: Austin Stoner, Li Fu, LaShae Nicholson, Chao Zheng, Takuya Toyonaga, Joshua Spurrier, Will Laird, Zhengxin Cai and Stephen M. Strittmatter | Summary: Background Cellular prion protein (PrPC) is a high-affinity cell-surface receptor for Amyloid-β oligomers (Aßo). In certain overexpression models of Alzheimer’s Disease (AD), pharmacology and genetics demonstrate its […]

Clumpy wind studies and the non-detection of cyclotron line in OAO 1657-415

Kavli Affiliate: Deepto Chakrabarty | First 5 Authors: Pragati Pradhan, Carlo Ferrigno, Biswajit Paul, Enrico Bozzo, Ileyk El Mellah | Summary: Winds of massive stars are suspected to be inhomogeneous (or clumpy), which biases the measures of their mass loss rates. In High Mass X-ray Binaries (HMXBs), the compact object can be used as an […]
