AT2019pim: A Luminous Orphan Afterglow from a Moderately Relativistic Outflow

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 […]

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

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 […]

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

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 […]

Photoevaporation from Inner Protoplanetary Disks Confronted with Observations

Kavli Affiliate: Lile Wang | First 5 Authors: Yiren Lin, Lile Wang, Min Fang, Ahmad Nemer, Jeremy Goodman | Summary: The decades-long explorations on the dispersal of protoplanetary disks involve many debates about photoevaporation versus magnetized wind launching mechanisms. This letter argues that the observed winds originating from the inner disk ($Rlesssim 0.3$ AU) cannot […]

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

Kavli Affiliate: Eric Miller | First 5 Authors: Michael Wojnowicz, Preetish Rath, Eric Miller, Jeffrey Miller, Clifford Hancock | Summary: We seek to model a collection of time series arising from multiple entities interacting over the same time period. Recent work focused on modeling individual time series is inadequate for our intended applications, where collective […]

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

Kavli Affiliate: Hu Zhan | First 5 Authors: Zun Luo, Wei Du, Baocun Chen, Xianmin Meng, Hu Zhan | Summary: Precision measurements of astrometry and photometry 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 […]
