ALMA's sharpest view of IRAS 08544-4431: Unveiling the dust distribution asymmetries in the circumbinary disk

Maksym Mohorian, Devika Kamath, Elizabeth Cappellazzo +10

The interactions between post-asymptotic giant branch (post-AGB) binaries and their circumbinary disks play a central role in shaping the evolution of these systems. Circumbinary d…

Investigating black hole accretion and feedback self-regulation in Seyfert galaxies using the FIRE-3 cosmological hydrodynamic simulations

Jonathan Mercedes-Feliz, Daniel Anglés-Alcázar, Jose Cevallos +12

Recent observations of local Seyfert galaxies show an intriguing connection between Active Galactic Nuclei (AGN) luminosity and a deficit of molecular gas on ~50pc scales compared…

Detection of a four-carbon sugar in interstellar space

Izaskun Jimenez-Serra, Juan Garcia de la Concepcion, Herma M. Cuppen +19

Sugars are essential biomolecules, serving as metabolic fuels, nucleic acid backbone components, and structural or energy-storage polymers. A central question in origin-of-life res…
