Dense gas in luminous infrared galaxies [PDF]

Astronomy & Astrophysics, 2007
Molecules that trace the high-density regions of the interstellar medium have been observed in (ultra-)luminous (far-)infrared galaxies, in order to initiate multiple-molecule multiple-transition studies to evaluate the physical and chemical environment of the nuclear medium and its response to the ongoing nuclear activity. The HCN(1-0), HNC(1-0), HCO+(

Arp 299-A: More than "just" a prolific supernova factory [PDF]

, 2010
We present partial results from our monitoring of the nuclear region of the starburst galaxy IC 694 (=Arp 299-A) at radio wavelengths, aimed at discovering recently exploded core-collapse supernovae, as well as to determine their rate of explosion, which

Early assembly of the most massive galaxies [PDF]

, 2009
The current consensus is that galaxies begin as small density fluctuations in the early Universe and grow by in situ star formation and hierarchical merging(1).

Spectroscopy of Luminous Infrared Galaxies [PDF]

Symposium - International Astronomical Union, 1999
A review of recent optical and infrared spectroscopic results on luminous infrared galaxies is presented. The main emphasis is on the ultraluminous objects. Possible correlations with infrared luminosity are identified. These results are used to constrain the nature of the dominant energy source in luminous infrared galaxies, and to test whether these ...

First results from SPIFFI, II: The luminous infrared galaxy NGC 6240 and the luminous sub-millimeter galaxy SMMJ 14011+0252 [PDF]

, 2004
This is the second of two papers (I: Horrobin et al. 2003) on the first scientific results from the SPIFFI integral field spectrometer at the VLT. Here we discuss the observations and properties of the prototypical luminous infrared galaxy NGC 6240 and ...

Evolution of the ISM in luminous infrared galaxies [PDF]

Astronomy and Astrophysics, 2010
Aims. Molecules that trace the high-density regions of the interstellar medium may be used to evaluate the changing physical and chemical environment during the ongoing nuclear activity in (ultra-) luminous infrared galaxies (ULIRGs).Methods. The changing ratios of the HCN (1-0), HNC (1-0), HCO(+) (1-0), CN (1-0) and CN (2-1), and CS (3-2) transitions ...

The Dragonfly Galaxy. III. Jet Brightening of a High-redshift Radio Source Caught in a Violent Merger of Disk Galaxies

The Astrophysical Journal, 2023
The Dragonfly galaxy (MRC 0152-209), the most infrared-luminous radio galaxy at redshift z ∼ 2, is a merger system containing a powerful radio source and large displacements of gas.
