JWST MIRI flight performance: Detector Effects and Data Reduction Algorithms
Jane Morrison, Daniel Dicken, Ioannis Argyriou +21
The detectors in the Mid-Infrared Instrument (MIRI) of the James Webb Space Telescope (JWST) are arsenic-21 doped silicon impurity band conduction (Si:As IBC) devices and are direc…
MOMO VI: Multifrequency radio variability of the blazar OJ 287 from 2015-2022, absence of predicted 2021 precursor-flare activity, and a new binary interpretation of the 2016/2017 outburst
S. Komossa, A. Kraus, D. Grupe +12
Based on our dedicated Swift monitoring program, MOMO, OJ 287 is one of the best-monitored blazars in the X-ray--UV--optical regime. Here, we report results from our accompanying,…
The globular clusters and star formation history of the isolated, quiescent ultra-diffuse galaxy DGSAT I
Steven R. Janssens, Aaron J. Romanowsky, Roberto Abraham +6
We investigate the isolated, quiescent ultra-diffuse galaxy (UDG) DGSAT I and its globular cluster (GC) system using two orbits of Hubble Space Telescope Advanced Camera for Survey…
Still at Odds with Conventional Galaxy Evolution: The Star Formation History of Ultra-Diffuse Galaxy Dragonfly 44
Kristi A. Webb, Alexa Villaume, Seppo Laine +7
We study the star formation history (SFH) of the ultra-diffuse galaxy (UDG) Dragonfly 44 (DF44) based on the simultaneous fit to near-ultraviolet to near-infrared photometry and hi…
The stellar populations of quiescent ultra-diffuse galaxies from optical to mid-infrared spectral energy distribution fitting
Maria Luisa Buzzo, Duncan A. Forbes, Jean P. Brodie +8
We use spectral energy distribution (SED) fitting to place constraints on the stellar population properties of 29 quiescent ultra-diffuse galaxies (UDGs) across different environme…
Multiwavelength astrophysics of the blazar OJ 287 and the project MOMO
S. Komossa, A. Kraus, D. Grupe +19
We are carrying out the densest and longest multiyear, multiwavelength monitoring project of OJ 287 ever done. The project MOMO (Multiwavelength Observations and Modelling of OJ 28…
