Expanding the Ice Inventory of NGC 1333 IRAS 2A with INDRA using JWST Observations: Tracing Organic Refractories and Beyond
Prathap Rayalacheruvu, Liton Majumdar, W. R. M. Rocha +7
In the era of JWST, with its unprecedented sensitivity and spectral resolution, infrared spectral surveys have revealed a rich inventory of ices, including complex organic molecule…
Revealing Potential Initial Mass Function variations with metallicity: JWST observations of young open clusters in a low-metallicity environment
Chikako Yasui, Natsuko Izumi, Masao Saito +3
We present the substellar mass function of star-forming clusters (0.1 Myr old) in a low-metallicity environment (0.7 dex). We performed deep JWST/NIRCam and MIRI…
Overview Results of JWST Observations of Star-Forming Clusters in the Extreme Outer Galaxy
Natsuko Izumi, Michael E. Ressler, Ryan M. Lau +4
The extreme outer Galaxy (EOG), which we define as the region of the Milky Way with a galactocentric radius of more than 18 kpc, provides an excellent opportunity to study star for…
Mid-infrared fine structure lines from the Galactic Warm Ionized Medium
S. R. Kulkarni, Charles Beichman, Michael E. Ressler
Galaxy and occupies perhaps a quarter of the volume of the Galactic disk. Decoding the spectrum of the Galactic diffuse ionizing field is of fundamental interest. This can be done…
Detection of HOCO+ in the protostar IRAS 16293-2422
Liton Majumdar, Pierre Gratier, Valentine Wakelam +3
The protonated form of CO2, HOCO+, is assumed to be an indirect tracer of CO2 in the millimeter/submillimeter regime since CO2 lacks a permanent dipole moment. Here, we report the…
Evidence from SOFIA Imaging of Polycyclic Aromatic Hydrocarbon Formation along a Recent Outflow in NGC 7027
R. M. Lau, M. Werner, R. Sahai +1
We report spatially resolved (FWHM) mid-IR imaging observations of the planetary nebula (PN) NGC 7027 taken with the 2.5-m telescope aboard the Stratospheric Observat…
