The Ultraviolet Slopes of Early Universe Galaxies: The Impact of Bursty Star Formation, Dust, and Nebular Continuum Emission [PDF]

The Astrophysical Journal
JWST has enabled the detection of the ultraviolet (UV) continuum of galaxies at z > 10, revealing extremely blue, potentially dust-free galaxies. However, interpreting UV spectra is complicated by the well-known degeneracy between stellar ages, dust ...

The ALMA REBELS Survey: dust continuum detections at z > 6.5 [PDF]

, 2022
We report 18 dust continuum detections (≥3.3σ) at ∼88 and 158 $\mu{\rm m}$ out of 49 ultraviolet (UV)-bright galaxies (MUV < -21.3 mag) at $z$ > 6.5, observed by the Cycle-7 Atacama Large Millimeter/submillimeter Array (ALMA) Large Program ...

Observability of photoevaporation signatures in the dust continuum emission of transition discs

Monthly Notices of the Royal Astronomical Society, 2023
ABSTRACT Photoevaporative disc winds play a key role in our understanding of circumstellar disc evolution, especially in the final stages, and they might affect the planet formation process and the final location of planets. The study of transition discs (i.e.

MULTI-WAVELENGTH RADIO CONTINUUM EMISSION STUDIES OF DUST-FREE RED GIANTS [PDF]

The Astronomical Journal, 2013
Multi-wavelength centimeter continuum observations of non-dusty, non-pulsating K spectral-type red giants directly sample their chromospheres and wind acceleration zones. Such stars are feeble emitters at these wavelengths however, and previous observations have provided only a small number of modest S/N measurements slowly accumulated over three ...

Dust formation and evolution in the ejecta of core-collapse supernovae [PDF]

, 2015
Observations of local supernovae over the past couple of decades have reported the presence of dust in the ejecta. The dust masses inferred from observations in mid-infrared and submillimeter wavelengths differ by a factor of 10^2 to 10^4 The composition

The dust-continuum size of TNG50 galaxies at z = 1–5: a comparison with the distribution of stellar light, stars, dust, and H₂ [PDF]

, 2021
We present predictions for the extent of the dust-continuum emission of main-sequence galaxies drawn from the TNG50 simulation in the range z = 1–5. We couple the radiative transfer code SKIRT to the output of the TNG50 simulation and measure the dust ...

We present updated measurements of the [O iii] 88 μm, [C ii] 158 μm, and dust continuum emission from a star-forming galaxy at z = 7.212, SXDF-NB1006-2, by utilizing Atacama Large Millimeter/submillimeter Array (ALMA) archival data sets analysed in ...

Millimeter dust continuum emission revealing the true mass of giant molecular clouds in the Small Magellanic Cloud [PDF]

Astronomy & Astrophysics, 2007
CO observations have been so far the best way to trace molecular gas in external galaxies, but at low metallicity the gas mass deduced could be largely underestimated. At present, the kinematic information of CO data cubes are used to estimate virial masses and trace the total mass of the molecular clouds. Millimeter dust emission can also be used as a

Comparing Molecular Gas Tracers at z~2: Do CO and dust continuum emission trace the same regions of the ISM?

, 2020
We have compared resolved and unresolved observations of the CO and dust continuum emission from star-forming galaxies at z~2 (taken with ALMA). The molecular gas phase of the interstellar medium is a crucial component of star-forming galaxies, hosting ...
