HELM's deep: Highly Extincted Low-Mass galaxies seen by JWST
L. Bisigello, G. Gandolfi, A. Grazian +25
The dust content of star-forming galaxies is generally positively correlated with their stellar mass. However, some recent JWST studies have shown the existence of a population of…

MIRI spectrophotometry of GN-z11: Detection and nature of an optical red continuum component
A. Crespo Gómez, L. Colina, P. G. Pérez-González +16
We present new MIRI F560W, F770W and F1000W imaging of GN-z11, extending the previous rest-frame coverage from 0.38 to 0.86m. We report significant detections (14) in the F56…
JWST observations of photodissociation regions III. Dust modelling at the illuminated edge of the Horsehead PDR
M. Elyajouri, A. Abergel, N. Ysard +19
Carbonaceous nano-grains are a significant component of interstellar dust and dominate the mid-infrared emission of photodissociation regions (PDRs). We study the evolution of nano…
Photometrically Selected Protocluster Candidates at z~9-10 in the JWST COSMOS-Web field
Cossas K. -W. Wu, Chih-Teng Ling, Tomotsugu Goto +8
High-redshift protoclusters are crucial for understanding the formation of galaxy clusters and the evolution of galaxies in dense environments. The James Webb Space Telescope (JWST…
The z = 9.625 Cosmic Gems Galaxy was a "Compact Blue Monster" Propelled by Massive Star Clusters
E. Vanzella, M. Messa, A. Adamo +36
The recent discovery of five massive stellar clusters at z=9.625 in the Cosmic Gems has raised the question about the formation mechanism of star clusters in the first half Gyr aft…
MIDIS: Quantifying the AGN component of X-ray-detected galaxies
Steven Gillman, John P. Pye, Almudena Alonso-Herrero +26
We combine the deepest X-ray survey from the Chandra Deep Field-South (CDF-S) `7-Ms' survey with the deepest mid-infrared (5.6) image from the JWST/MIRI Deep Imaging Survey (M…
The orbit and stellar masses of the archetype colliding-wind binary WR 140
Joshua D. Thomas, Noel D. Richardson, J. J. Eldridge +33
We present updated orbital elements for the Wolf-Rayet (WR) binary WR\,140 (HD\,193793; WC7pd + O5.5fc). The new orbital elements were derived using previously published measuremen…
An extensive spectroscopic time series of three Wolf-Rayet stars -- II. A search for wind asymmetries in the dust-forming WC7 binary WR137
N. St-Louis, C. Piaulet, N. D. Richardson +39
We present the results of a four-month, spectroscopic campaign of the Wolf-Rayet dust-making binary, WR137. We detect only small-amplitude, random variability in the CIII5696 emiss…
Infrastructure and Strategies for Time Domain and MMA and Follow-Up
B. W. Miller, L. Allen, E. Bellm +28
Time domain and multi-messenger astrophysics are growing and important modes of observational astronomy that will help define astrophysics in the 2020s. Significant effort is being…
On the need for synthetic data and robust data simulators in the 2020s
Molly S. Peeples, Bjorn Emonts, Mark Kyprianou +6
As observational datasets become larger and more complex, so too are the questions being asked of these data. Data simulations, i.e., synthetic data with properties (pixelization,…
BRITE-Constellation high-precision time-dependent photometry of the early-O-type supergiant Puppis unveils the photospheric drivers of its small- and large-scale wind structures
Tahina Ramiaramanantsoa, Anthony F. J. Moffat, Robert Harmon +33
From months of dual-band optical photometric monitoring at the mmag level, BRITE-Constellation has revealed two simultaneous types of variability in the O4I(n)fp star …
The variability of the BRITE-est Wolf-Rayet binary, Velorum I. Photometric and spectroscopic evidence for colliding winds
Noel D. Richardson, Christopher M. P. Russell, Lucas St-Jean +26
We report on the first multi-color precision light curve of the bright Wolf-Rayet binary Velorum, obtained over six months with the nanosatellites in the BRITE- Constellation…
An extensive spectroscopic time-series of three Wolf-Rayet stars. I. The lifetime of large-scale structures in the wind of WR 134
