Spin vectors in the Koronis family: IV. Completing the sample of its largest members after 35 years of study

Stephen M. Slivan, Matthew Hosek, Max Kurzner +17

An observational study of Koronis family members' spin properties was undertaken with two primary objectives: to reduce selection biases for object rotation period and lightcurve a…

The Impact of Initial-Final Mass Relations on Black Hole Microlensing

Sam Rose, Casey Y. Lam, Jessica R. Lu +5

Uncertainty in the initial-final mass relation (IFMR) has long been a problem in understanding the final stages of massive star evolution. One of the major challenges of constraini…

AIROPA IV: Validating Point Spread Function Reconstruction on Various Science Cases

Sean K. Terry, Jessica R. Lu, Paolo Turri +7

We present an analysis of six independent on-sky datasets taken with the Keck-II/NIRC2 instrument. Using the off-axis point spread function (PSF) reconstruction software AIROPA, we…

Measuring the Orbits of the Arches and Quintuplet Clusters using HST and Gaia: Exploring Scenarios for Star Formation Near the Galactic Center

Matthew W. Hosek, Tuan Do, Jessica R. Lu +4

We present new absolute proper motion measurements for the Arches and Quintuplet clusters, two young massive star clusters near the Galactic center. Using multi-epoch HST observati…

Searching for a Hypervelocity White Dwarf Companion: A Proper Motion Survey of SN 1006

Joshua V. Shields, Wolfgang Kerzendorf, Matthew W. Hosek +7

Type Ia Supernovae (SNe Ia) are securely understood to come from the thermonuclear explosion of a white dwarf as a result of binary interaction, but the nature of that binary inter…
