JWST reveals a possible galaxy merger in triply-lensed MACS0647JD

Tiger Yu-Yang Hsiao, Dan Coe, Abdurro'uf +63

MACS0647JD is a triply-lensed galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647JD as ha…

Resolving the inner parsec of the blazar J1924-2914 with the Event Horizon Telescope

Sara Issaoun, Maciek Wielgus, Svetlana Jorstad +27

The blazar J1924-2914 is a primary Event Horizon Telescope (EHT) calibrator for the Galactic Center's black hole Sagittarius A*. Here we present the first total and linearly polari…

Principal-Component Interferometric Modeling (PRIMO), an Algorithm for EHT Data I: Reconstructing Images from Simulated EHT Observations

Lia Medeiros, Dimitrios Psaltis, Tod R. Lauer +1

The sparse interferometric coverage of the Event Horizon Telescope (EHT) poses a significant challenge for both reconstruction and model fitting of black-hole images. PRIMO is a ne…

A Near Surface Temperature Model of Arrokoth

O. M. Umurhan, W. M. Grundy, M. K. Bird +19

A near surface thermal model for Arrokoth is developed based on the recently released facet model of the body. This thermal solution takes into account Arrokoth's surface re…
