Dust destruction by the supernova remnant forward shock in a turbulent interstellar medium
Tassilo Scheffler, Nina S. Sartorio, Florian Kirchschlager +3
Context. While supernova remnants (SNRs) are observed to produce up to 1 M of dust, the amount of dust destroyed by the forward shock (FS) is poorly constrained, raising th…
REBELS-IFU: Evidence for metal-rich massive galaxies at z~6-8
Lucie E. Rowland, Mauro Stefanon, Rychard Bouwens +30
Metallicity is a crucial tracer of galaxy evolution, providing insights into gas accretion, star formation, and feedback. At high redshift, these processes reveal how early galaxie…
REBELS-IFU: Dust attenuation curves of 12 massive galaxies at
Rebecca Fisher, Rebecca A. A. Bowler, Mauro Stefanon +17
We present measurements of the dust attenuation curves of 12 massive (( ) Lyman-break galaxies at derived from James Webb Space…
Full disc [CII] mapping of nearby star-forming galaxies: SOFIA FIFI/LS observations of NGC 3627, NGC 4321, and NGC 6946
I. Kovačić, A. T. Barnes, F. Bigiel +20
As a major cooling line of interstellar gas, the far-infrared 158 μm line from singly ionised carbon [CII] is an important tracer of various components of the interstellar medium i…
The Green Monster hiding in front of Cas A: JWST reveals a dense and dusty circumstellar structure pockmarked by ejecta interactions
Ilse De Looze, Dan Milisavljevic, Tea Temim +27
JWST observations of the young Galactic supernova remnant Cassiopeia A revealed an unexpected structure seen as a green emission feature in colored composite MIRI F1130W and F1280W…
Shockingly Bright Warm Carbon Monoxide Molecular Features in the Supernova Remnant Cassiopeia A Revealed by JWST
J. Rho, S. -H. Park, R. Arendt +36
We present JWST NIRCam (F356W and F444W filters) and MIRI (F770W) images and NIRSpec- IFU spectroscopy of the young supernova remnant Cassiopeia A (Cas A). We obtained the data as…
Gravitational waves from mergers of Population III binary black holes: roles played by two evolution channels
Boyuan Liu, Tilman Hartwig, Nina S. Sartorio +6
The gravitational wave (GW) signal from binary black hole (BBH) mergers is a promising probe of Population III (Pop III) stars. To fully unleash the power of the GW probe, one impo…
From total destruction to complete survival: Dust processing at different evolutionary stages in the supernova remnant Cassiopeia A
Florian Kirchschlager, Nina Sartorio, Ilse De Looze +3
The expanding ejecta of supernova remnants (SNRs) are believed to form dust in dense clumps of gas. Before the dust can be expelled into the interstellar medium and contribute to t…
A JWST Survey of the Supernova Remnant Cassiopeia A
Dan Milisavljevic, Tea Temim, Ilse De Looze +43
We present initial results from a JWST survey of the youngest Galactic core-collapse supernova remnant Cassiopeia A (Cas A), made up of NIRCam and MIRI imaging mosaics that map emi…

We present and publicly release a new star-forming regions emission library TODDLERS (Time evolution of Observables including Dust Diagnostics and Line Emission from Regions contai…
Population synthesis of Be X-ray binaries: metallicity dependence of total X-ray outputs
Boyuan Liu, Nina S. Sartorio, Robert G. Izzard +1
X-ray binaries (XRBs) are thought to regulate cosmic thermal and ionization histories during the Epoch of Reionization and Cosmic Dawn ().Theoretical predictions of the…
Population III X-ray Binaries and their Impact on the Early Universe
Nina S. Sartorio, A. Fialkov, T. Hartwig +8
The first population of X-ray binaries (XRBs) is expected to affect the thermal and ionization states of the gas in the early Universe. Although these X-ray sources are predicted t…
Cosmic Web Dissection in Fuzzy Dark Matter Cosmologies
Tibor Dome, Anastasia Fialkov, Nina Sartorio +1
On large cosmological scales, anisotropic gravitational collapse is manifest in the dark cosmic web. Its statistical properties are little known for alternative dark matter models…
Dust survival rates in clumps passing through the Cas A reverse shock -- II. The impact of magnetic fields
Florian Kirchschlager, Franziska D. Schmidt, M. J. Barlow +2
Dust grains form in the clumpy ejecta of core-collapse supernovae where they are subject to the reverse shock, which is able to disrupt the clumps and destroy the grains. Important…
Impact of the Primordial Stellar Initial Mass Function on the 21-cm Signal
T. Gessey-Jones, N. S. Sartorio, A. Fialkov +6
Properties of the first generation of stars (Pop III), such as their initial mass function (IMF), are poorly constrained by observations and have yet to converge between simulation…
What it Takes to Measure Reionization with Fast Radio Bursts
Stefan Heimersheim, Nina S. Sartorio, Anastasia Fialkov +1
Fast Radio Bursts (FRBs) are extra-galactic radio transients which exhibit a distance-dependent dispersion of their signal, and thus can be used as cosmological probes. In this art…
