Gas-phase Fe/O and Fe/N abundances in Star-Forming Regions. Relations between nucleosynthesis, metallicity and dust
J. E. Méndez-Delgado, K. Kreckel, C. Esteban +10
In stars, metallicity is usually traced using Fe, while in nebulae, O serves as the preferred proxy. Both elements have different nucleosynthetic origins and are not directly compa…
The ALMA-CRISTAL survey: Extended [CII] emission in an interacting galaxy system at z ~ 5.5
A. Posses, M. Aravena, J. González-López +31
The ALMA [CII] Resolved Ism in STar-forming gALaxies (CRISTAL) survey is a Cycle 8 ALMA Large Programme that studies the cold gas component of high-redshift galaxies. Its sub-arcse…
Observational signatures of the dust size evolution in isolated galaxy simulations
Kosei Matsumoto, Hiroyuki Hirashita, Kentaro Nagamine +9
We aim to provide observational signatures of the dust size evolution in the ISM. In particular, we explore indicators of the polycyclic aromatic hydrocarbon (PAH) mass fraction ($…
The ALMA-CRISTAL survey. Discovery of a 15 kpc-long gas plume in a Lyman- blob
M. Solimano, J. González-López, M. Aravena +24
Massive star-forming galaxies in the high-redshift universe host large reservoirs of cold gas in their circumgalactic medium (CGM). Traditionally, these reservoirs have been linked…
The ALMA-CRISTAL survey: Widespread dust-obscured star formation in typical star-forming galaxies at z=4-6
Ikki Mitsuhashi, Ken-ichi Tadaki, Ryota Ikeda +29
We present the morphological parameters and global properties of dust-obscured star formation in typical star-forming galaxies at z=4-6. Among 26 galaxies composed of 20 galaxies o…
Metal and dust evolution in ALMA REBELS galaxies: insights for future JWST observations
Marco Palla, Ilse De Looze, Monica Relaño +16
ALMA observations revealed the presence of significant amounts of dust in the first Gyr of Cosmic time. However, the metal and dust buildup picture remains very uncertain due to th…
