A Population of Short-duration Gamma-ray Bursts with Dwarf Host Galaxies

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Anya E. Nugent, Wen-fai Fong, Cristian Castrejon, Joel Leja, Michael Zevin | Summary: We present a population of 11 of the faintest ($> 25.5$ AB mag) short gamma-ray burst (GRB) host galaxies. We model their sparse available observations using the stellar population inference code Prospector-$beta$ and […]

A Dataset for Exploring Stellar Activity in Astrometric Measurements from SDO Images of the Sun

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Warit Wijitworasart, Zoe de Beurs, Andrew Vanderburg, , | Summary: We present a dataset for investigating the impact of stellar activity on astrometric measurements using NASA’s Solar Dynamics Observatory (SDO) images of the Sun. The sensitivity of astrometry for detecting exoplanets is limited by stellar activity (e.g. […]

Simulating medium-spectral-resolution exoplanet characterization with SCALES angular/reference differential imaging

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Aditi Desai, Stephanie E. Sallum, Ravinder Banyal, Natalie Batalha, Natasha Batalha | Summary: SCALES (Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy) is a 2 – 5 micron high-contrast lenslet-based integral field spectrograph (IFS) designed to characterize exoplanets and their atmospheres. The SCALES medium-spectral-resolution mode uses […]

Neural activity ramps in frontal cortex signal extended motivation during learning

Kavli Affiliate: Priya Rajasethupathy | Authors: Josue M Regalado, Ariadna Corredera Asensio, Theresa Haunold, Andrew C Toader, Yan Ran Li, Lauren A Neal and Priya Rajasethupathy | Summary: Learning requires the ability to link actions to outcomes. How motivation facilitates learning is not well understood. We designed a behavioral task in which mice self-initiate trials […]
