We present spatially resolved ALMA [CII] observations of the bright (flux density S350 =400 mJy at 350 μm), gravitationally lensed, starburst galaxy PLCK G045.1+61.1 at z = 3.427, the “Garnet”. This source is part of our set of “Planck’s Dusty GEMS”, discovered with the Planck’s all-sky survey. Two emission-line clouds with a relative velocity offset of ∼ 600 km s−1 extend towards north-east an...

The impact of polymer removal by forming gas and vacuum annealing on the doping, strain, and morphology of chemical vapor deposited (CVD) and mechanically exfoliated (ME) graphene is investigated using Raman spectroscopy and atomic force microscopy (AFM). The behavior of graphene exposed and unexposed to polymer is compared. It is found that the well-known doping effect after forming gas anneal...

Stephan’s Quintet (SQ) is a Hickson Compact Group well known for its complex dynamical and star formation history and its rich intergalactic medium (IGM). In order to study the extent, origin and fate of the intergalactic molecular gas and its relation to the formation of stars outside galaxies and Tidal Dwarf Galaxies (TDGs), we mapped with the IRAM 30m antenna carbon monoxide (CO) towards sev...

I review the properties of the interstellar medium in the Magellanic Clouds and Local Group dwarf galaxies. The more massive, star-forming galaxies show a complex, multi-phase ISM full of shells and holes ranging from very cold phases (a few 10 K) to extremely hot gas (> 10 K). In environments with high UV radiation fields the formation of molecular gas is suppressed, while in dwarfs with low U...

We use cosmological simulations to study the origin of primordial star-forming clouds in a CDM universe, by following the formation of dark matter halos and the cooling of gas within them. To model the physics of chemically pristine gas, we employ a nonequilibrium treatment of the chemistry of nine species (e , H, H+, He, He+, He++, H2, H þ 2 , H ) and include cooling by molecular hydrogen. By ...

We present a detailed, physically grounded, model for the early coevolution of spheroidal galaxies and of active nuclei at their centers. The model is based on very simple recipes, that can be easily implemented. The main components and the transfer processes accounted for are depicted in Fig. 1, while we defer to Granato et al. (2004) for a full description. In summary, we start from the diffu...

The prominent interacting galaxy pair NGC 4038/9 contains many active star-forming regions and is continuously forming new star clusters. We present a self-consistent n-body model for this system which includes an SPH gas component. The model qualitatively explains the apparent concentration of gas in the so-called overlap region between the two nuclei as a bridge of gas connecting the two gala...

The preliminary results from a deep emission-line search for warm ionized material in the halos of nearby active and star-forming galaxies are presented. The origin of this gas is discussed in the context of galaxy formation and evolution.
