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

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 […]

Unraveling emission line galaxy conformity at z~1 with DESI early data

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Sihan Yuan, Risa H. Wechsler, Yunchong Wang, Mithi A. C. de los Reyes, Justin Myles | Summary: Emission line galaxies (ELGs) are now the preeminent tracers of large-scale structure at z>0.8 due to their high density and strong emission lines, which enable accurate redshift measurements. However, […]

The classical field approximation of ultra light dark matter: quantum breaktimes, corrections, and decoherence

Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Alvaro Zamora, Michael Kopp, Tom Abel, | Summary: The classical field approximation is widely used to better understand the predictions of ultra-light dark matter. Here, we use the truncated Wigner approximation method to test the classical field approximation of ultra-light dark matter. This method approximates […]
