Laser Metrology for Precision Alignment of Transmission Gratings in the REDSoX Soft X-ray Polarimeter
Swati Ravi, Alan Garner, Jill Juneau +4
The Rocket Experiment Demonstration of a Soft X-ray Polarimeter (REDSoX) is a NASA sounding-rocket mission designed to perform the first astrophysical spectropolarimetry in the 0.2…
Active Galactic Nucleus Tori: Potential Birthplace to Millions of Planets
Bhupendra Mishra, Wladimir Lyra, Barry McKernan +3
The outer regions of AGN disks have temperatures similar to those of circumstellar disks, permitting dust condensation. Therefore, planet formation and growth could be active in th…
Image reconstruction with the JWST Interferometer
Max Charles, Louis Desdoigts, Benjamin Pope +7
Flying on board the James Webb Space Telescope (JWST) above Earth's turbulent atmosphere, the Aperture Masking Interferometer (AMI) on the NIRISS instrument is the highest-resoluti…
AGN Disks as Supernova Mufflers I: 3D Local Hydrodynamic Models
Harrison E. Cook, Wladimir Lyra, Mordecai-Mark Mac Low +2
Supernova (SN) shocks that originate from stars on orbits embedded in dense active galactic nuclei (AGN) accretion disks evolve differently from those that occur in the interstella…
McFACTS. IV. Electromagnetic Counterparts to AGN-disk-embedded Binary Black Hole Mergers
Emily McPike, Rosalba Perna, K. E. Saavik Ford +10
The accretion disks of active galactic nuclei (AGNs) are promising environments for producing binary black hole (BBH) mergers, which have been detected via gravitational waves (GWs…
An Extremely Luminous Flare Recorded from a Supermassive Black Hole
Matthew J. Graham, Barry McKernan, K. E. Saavik Ford +17
Since their discovery more than 60 years ago, accreting supermassive black holes in active galactic nuclei (AGN) were recognized as highly variable sources, requiring an extremely…
