Resolving the temporal evolution of M87 jet with -arcsec Chandra observations

Camille Poitras, Gerrit Schellenberger, Ralph Kraft +3

We present a 13-year Chandra/HRC-I study of the M87 jet, using point-spread-function deconvolution to achieve unprecedented sub-arcsecond X-ray resolution of its kiloparsec-scale s…

Detection of CO ice in the planetary nebula NGC 6302

Charmi Bhatt, Simon W. Cao, Jan Cami +20

Using JWST/MIRI observations, we report the detection of CO ice in the dusty torus of the planetary nebula NGC 6302, an environment generally considered hostile to fragile mole…

VLBA Detections in the Oph-S1 Binary System near Periastron Confirmation of its Orbital Elements and Mass

Jazmín Ordóñez-Toro, Sergio A. Dzib, Laurent Loinard +7

Oph-S1 is the most luminous and massive stellar member of the nearby Ophiuchus star-forming region. Previous Very Long Baseline Array (VLBA) observations have shown it to be an int…
