Pumping the brakes on RNA velocity – understanding and interpreting RNA velocity estimates

Posted by klaurent Hopkins

Kavli Affiliate: Loyal Goff | Authors: Shijie C. Zheng, Genevieve Stein-O’Brien, Leandros Boukas, Loyal A Goff and Kasper D Hansen | Summary: RNA velocity analysis of single cells promises to predict temporal dynamics from gene expression. Indeed, in many systems, it has been observed that RNA velocity produces a vector field that qualitatively reflects known […]

The Tidal Disruption Event AT2021ehb: Evidence of Relativistic Disk Reflection, and Rapid Evolution of the Disk-Corona System

Posted by klaurent MIT

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Yuhan Yao, Wenbin Lu, Muryel Guolo, Dheeraj R. Pasham, Suvi Gezari | Summary: We present X-ray, UV, optical, and radio observations of the nearby ($approx78$ Mpc) tidal disruption event (TDE) AT2021ehb/ZTF21aanxhjv during its first 430 days of evolution. AT2021ehb occurs in the nucleus of a galaxy […]
