The Background Interstellar Medium as Observed from Off-Order Low-Resolution Spitzer-IRS Spectra

Autor: Boersma, Christiaan, Bregman, Jesse D., Allamandola, Louis J., Temi, Pasquale, Maragkoudakis, Alexandros

Spitzer 'hidden' observations of the background are used to construct a catalog of 4,090 spectra and examine the signature of polycyclic aromatic hydrocarbon (PAH) molecules and their connection to extinction by dust. A strong positive correlation is

Sampling Strategies for Mitigating Bias in Face Synthesis Methods

Autor: Maragkoudakis, Emmanouil, Papadopoulos, Symeon, Varlamis, Iraklis, Diou, Christos

Synthetically generated images can be used to create media content or to complement datasets for training image analysis models. Several methods have recently been proposed for the synthesis of high-fidelity face images; however, the potential biases

Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiation produces photo-dissociation regions (PDRs) on the surfaces of proto

Water is a key ingredient for the emergence of life as we know it. Yet, its destruction and reformation in space remains unprobed in warm gas. Here, we detect the hydroxyl radical (OH) emission from a planet-forming disk exposed to external far-ultra

JWST: Deuterated PAHs, PAH-nitriles, and PAH Overtone and Combination Bands I: Program Description and First Look

Autor: Boersma, C., Allamandola, L. J., Esposito, V. J., Maragkoudakis, A., Bregman, J. D., Temi, P., Lee, T. J., Fortenberry, R. C., Peeters, E.

A first look is taken at the NIRSpec 1-5 $\mu$m observations from JWST program 1591 that targets 7 objects along the low-mass stellar life cycle with PAH emission. Spectra extracted from a 1.5$^{\prime\prime}$ radius sized circular aperture are explo
