Molecular cloud formation as seen in synthetic Hi and molecular gas observations
Jonathan S. Heiner, Enrique Vázquez-Semadeni, Javier Ballesteros-Paredes
We present synthetic Hi and CO observations of a simulation of decaying turbulence in the thermally bistable neutral medium. We first present the simulation, with clouds initially…
Applying a one-dimensional PDR model to the Taurus molecular cloud and its atomic envelope
J. S. Heiner, E. Vázquez-Semadeni
In this contribution, we test our previously published one-dimensional PDR model for deriving total hydrogen volume densities from HI column density measurements in extragalactic r…
Hydrogen volume densities in nearby galaxies I - an automated approach
J. S. Heiner, J. R. Sánchez-Gallego, L. Rousseau-Nepton +1
Using a simple model of photodissociated atomic hydrogen on a galactic scale, it is possible to derive total hydrogen volume densities. These densities, obtained through a combinat…
Quantified H i Morphology VII: The Morphology of Extended Disks in UV and H i
B. W. Holwerda, N. Pirzkal, J. S. Heiner
Extended UltraViolet (xuv) disks have been found in a substantial fraction of late-type --S0, spiral and irregular-- galaxies. Similarly, most late-type spirals have an extended ga…
Atomic Hydrogen produced in M33 Photodissociation Regions
J. S. Heiner, R. J. Allen, P. C. van der Kruit
We derive total (atomic + molecular) hydrogen densities in giant molecular clouds (GMCs) in the nearby spiral galaxy M33 using a method that views the atomic hydrogen near regions…
The JCMT Nearby Galaxies Legacy Survey VI: The distribution of gas and star formation in M81
J. R. Sánchez-Gallego, J. H. Knapen, J. S. Heiner +12
We present a first complete 12 CO J=3-2 map of M81, observed as part of the Nearby Galaxies Legacy Survey being carried out at the James Clerk Maxwell Telescope. We detect 9 region…
