Isolating Sgr A East: The First Uncontaminated X-ray Maps of a Galactic Center Supernova Remnant
Mayura Balakrishnan, Adrien Picquenot, Lia Corales +3
The central few parsecs of the Milky Way host a complex X-ray-emitting environment in which several extended plasma components are blended along the line of sight, complicating att…
Probing the Molecular Hearts of Extreme Bipolar Planetary Nebulae with ALMA
Paula Moraga Baez, Joel H. Kastner, Jesse Bublitz +6
We present results from a program of Atacama Large Millimeter Array (ALMA) 1.3 mm (Band 6) molecular line mapping of a sample of nearby, bipolar/pinched-waist, molecule-rich PNe (N…
JWST/NIRCam imaging of the Bipolar Planetary Nebula NGC 6537: the (Infra)red Spider, Revealed
Joel Kastner, Paula Moraga Baez, Bruce Balick +5
We present James Webb Space Telescope (JWST) near-infrared (NIRCam) Br, H, [Fe II], and PAH imaging of the molecule-rich, high-excitation bipolar planetary nebula (PN) NGC…
Planetary Nebulae in the eROSITA eRASS1 catalog
Haoyang Yuan, Martin A. Guerrero, Quentin Parker +1
Some planetary nebulae (PNe) host X-ray-emitting hot bubbles shaped by stellar wind interactions and/or harbor X-ray-emitting central stars due to accretion, shocks within their fa…
The impact of periastron passage on the X-ray and optical properties of the Symbiotic System R Aquarii
D. A. Vásquez-Torres, J. A. Toalá, A. Sacchi +4
Multi-epoch Chandra and XMM-Newton observations of the symbiotic system R Aquarii (R Aqr) spanning 22 yr are analysed by means of a reflection model produced by an accretion disc.…
