SAGAbg I: A Near-Unity Mass Loading Factor in Low-Mass Galaxies via their Low-Redshift Evolution in Stellar Mass, Oxygen Abundance, and Star Formation Rate

Posted by dbos Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Erin Kado-Fong, Marla Geha, Yao-Yuan Mao, Mithi A. C. de los Reyes, Risa H. Wechsler | Summary: Measuring the relation between star formation and galactic winds is observationally difficult. In this work we make an indirect measurement of the mass loading factor (the ratio between mass […]

AT2019pim: A Luminous Orphan Afterglow from a Moderately Relativistic Outflow

Posted by dbos MIT

Kavli Affiliate: Michael Fausnaugh | First 5 Authors: Daniel A. Perley, Anna Y. Q. Ho, Michael Fausnaugh, Gavin P. Lamb, Mansi M. Kasliwal | Summary: Classical gamma-ray bursts (GRBs) have two distinct emission episodes: prompt emission from ultra-relativistic ejecta and afterglow from shocked circumstellar material. While both components are extremely luminous in known GRBs, a […]

The rigidity of eigenvalues on Kähler manifolds with positive Ricci lower bound

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Jianchun Chu, Feng Wang, Kewei Zhang, , | Summary: In this work, optimal rigidity results for eigenvalues on K"ahler manifolds with positive Ricci lower bound are established. More precisely, for those K"ahler manifolds whose first eigenvalue agrees with the Ricci lower bound, we show that the complex […]

Discovery of two warm mini-Neptunes with contrasting densities orbiting the young K3V star TOI-815

Posted by dbos MIT

Kavli Affiliate: Sara Seager | First 5 Authors: Angelica Psaridi, Hugh Osborn, François Bouchy, Monika Lendl, Léna Parc | Summary: We present the discovery and characterization of two warm mini-Neptunes transiting the K3V star TOI-815 in a K-M binary system. Analysis of the spectra and rotation period reveal it to be a young star with […]

FBM: Freestanding bilayer microscope for single-molecule imaging of membrane proteins

Posted by dbos Rockefeller

Kavli Affiliate: Roderick MacKinnon | Authors: Gonzalo Pérez-Mitta, Yeliz Sezgin, Weiwei Wang and Roderick MacKinnon | Summary: Abstract Integral membrane proteins (IMPs) constitute a large fraction of organismal proteomes, playing fundamental roles in physiology and disease. Despite their importance, the mechanisms underlying dynamic features of IMPs, such as anomalous diffusion, protein-protein interactions, and protein clustering, […]

Protocol for certifying entanglement in surface spin systems using a scanning tunneling microscope

Posted by dbos Delft

Kavli Affiliate: Sander Otte | First 5 Authors: Rik Broekhoven, Curie Lee, Soo-hyon Phark, Sander Otte, Christoph Wolf | Summary: Certifying quantum entanglement is a critical step towards realizing quantum-coherent applications of surface spin systems. In this work, we show that entanglement can be unambiguously shown in a scanning tunneling microscope (STM) with electron spin […]

Discovering group dynamics in coordinated time series via hierarchical recurrent switching-state models

Posted by dbos MIT

Kavli Affiliate: Eric Miller | First 5 Authors: Michael T. Wojnowicz, Kaitlin Gili, Preetish Rath, Eric Miller, Jeffrey Miller | Summary: We seek a computationally efficient model for a collection of time series arising from multiple interacting entities (a.k.a. "agents"). Recent models of spatiotemporal patterns across individuals fail to incorporate explicit system-level collective behavior that […]

Modeling the wavelength dependence of pixel response non-uniformity of a CCD sensor

Posted by dbos Peking

Kavli Affiliate: Hu Zhan | First 5 Authors: Zun Luo, Wei Du, Baocun Chen, Xianmin Meng, Hu Zhan | Summary: Precision measurements in astronomy require stringent control of systematics such as those arising from imperfect correction of sensor effects. In this work, we develop a parametric method to model the wavelength dependence of pixel response […]

On the Scarcity of Dense Cores ($n>10^{5}$ cm$^{-3}$) in High Latitude Planck Galactic Cold Clumps

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Fengwei Xu, Ke Wang, Tie Liu, David Eden, Xunchuan Liu | Summary: High-latitude ($|b|>30^{circ}$) molecular clouds have virial parameters that exceed 1, but whether these clouds can form stars has not been studied systematically. Using JCMT SCUBA-2 archival data, we surveyed 70 fields that target high-latitude Planck […]
