The radiation from stars and active galactic nuclei (AGNs) creates photodissociation regions
(PDRs) and X-ray-dominated regions (XDRs), where the chemistry or heating is dominated …

The discovery of galaxies with regularly rotating discs at redshifts≥ 4 has been a puzzling
challenge to galaxy formation models that tend to predict chaotic gas kinematics in the early …

The Hi gas content is a key ingredient in galaxy evolution, the study of which has been
limited to moderate cosmological distances for individual galaxies due to the weakness of …

A great deal of effort has been made in recent years to probe the gas fraction evolution of
massive quiescent galaxies (QGs); however, a clear picture has not yet been established …

Observations of local star-forming galaxies (SFGs) show a tight correlation between their
singly ionized carbon line luminosity () and star formation rate (SFR), suggesting that may be …

M82 is an archetypal starburst galaxy in the local Universe. The central burst of star
formation, thought to be triggered by M82's interaction with other members in the M81 group …

We address the puzzling observational indications for very 'cold'galactic discs at redshifts z≳
3, an epoch when discs are expected to be highly perturbed. Using a high-resolution …

Numerical models of photodissociation regions (PDRs) are an essential tool to quantitatively
understand observations of massive star forming regions through simulations. Few mature …

We investigate the physical structure and conditions of photodissociation regions (PDRs)
and molecular gas within the Pillars of Creation in the Eagle Nebula using SOFIA …

Extended [CII] emission on tens of kiloparsecs, also known as a [CII] halo, is currently being
reported around z∼ 4− 6 star-forming galaxies, especially thanks to the statistics of the …
