Multimode horn antennas for far-infrared astronomy [PDF]

The 8th European Conference on Antennas and Propagation (EuCAP 2014), 2014
Multi-mode horns combined with bolometric or incoherent detectors are finding application in astronomical receivers for which partially coherent operation can provide increased throughput and thus sensitivity. This is advantageous when observing faint sources, especially if diffraction limited resolution is not required, or if the horn beam is ...

Probing the Nature of the First Galaxies with JWST and ALMA

The Astrophysical Journal Letters, 2023
By implementing a model of primordial dust emission, we predict dust-continuum fluxes for massive galaxy sources similar to those recently detected by James Webb Space Telescope (JWST) at z ≳ 7.

Evidence for the Disruption of a Planetary System During the Formation of the Helix Nebula

The Astronomical Journal, 2022
The persistence of planetary systems after their host stars evolve into their post-main-sequence phase is poorly constrained by observations. Many young white dwarf systems exhibit infrared excess emission and/or spectral absorption lines associated with

A Rotating Accretion Disk around MWC 297, a Young B1.5Ve Star

The Astronomical Journal, 2023
High-resolution spectra with iSHELL on IRTF in the K and M bands of the young, heavily accreting B1.5Ve star MWC 297 show numerous double-peaked CO lines. These CO lines originate in an inclined gaseous disk in Keplerian rotation.
