Modeling Post-Reionization HI Distributions in Fuzzy Dark Matter Cosmologies Using Conditional Normalizing Flows

Posted by dbos Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Tibor Dome, Rumail Azhar, Anastasia Fialkov, , | Summary: Upcoming 21 cm intensity mapping experiments like the Square Kilometer Array (SKA) hold significant potential to constrain the properties of dark matter. In this work, we model neutral hydrogen (HI) distributions using high-resolution hydrodynamical $N$-body simulations of both […]

The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems IV: NIRISS Aperture Masking Interferometry Performance and Lessons Learned

Posted by dbos Stanford

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Steph Sallum, Shrishmoy Ray, Jens Kammerer, Anand Sivaramakrishnan, Rachel Cooper | Summary: We present a performance analysis for the aperture masking interferometry (AMI) mode on board the James Webb Space Telescope Near Infrared Imager and Slitless Spectrograph (JWST/NIRISS). Thanks to self-calibrating observables, AMI accesses inner working angles […]

ALMA gas-dynamical mass measurement of the supermassive black hole in the red nugget relic galaxy PGC 11179

Posted by dbos Peking

Kavli Affiliate: Luis Ho | First 5 Authors: Jonathan H. Cohn, Maeve Curliss, Jonelle L. Walsh, Kyle M. Kabasares, Benjamin D. Boizelle | Summary: We present 0$.!!^{primeprime}22$-resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations of CO(2$-$1) emission from the circumnuclear gas disk in the red nugget relic galaxy PGC 11179. The disk shows regular rotation, with […]

Dual-Band Observations of the Asymmetric Ring around CIDA 9A: Dead or Alive?

Posted by dbos Peking

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Daniel Harsono, Feng Long, Paola Pinilla, Alessia A. Rota, Carlo F. Manara | Summary: While the most exciting explanation of the observed dust asymmetries in protoplanetary disks is the presence of protoplanets, other mechanisms can also form the dust features. This paper presents dual-wavelength Atacama Large […]
