High-resolution molecular line observations of active galaxies
S. Garcia-Burillo, F. Combes, A. Usero +1
The study of the content, distribution and kinematics of interstellar gas is a key to understand the origin and maintenance of both starburst and nuclear (AGN) activity in galaxies…
Evidence of enhanced star formation efficiency in luminous and ultraluminous infrared galaxies
J. Gracia-Carpio, S. Garcia-Burillo, P. Planesas +2
We present new observations made with the IRAM 30m telescope of the J=1-0 and 3-2 lines of HCN and HCO^+ used to probe the dense molecular gas content in a sample of 17 local lumin…
A multi-transition HCN and HCO+ study of 12 nearby active galaxies: AGN versus SB environments
M. Krips, R. Neri, S. Garcia-Burillo +4
Recent studies have indicated that the HCN-to-CO(J=1-0) and HCO+-to-HCN(J=1-0) ratios are significantly different between galaxies with AGN (active galactic nucleus) and SB (starbu…
Sub-arcsecond CO(1-0) and CO(2-1) observations of the ultraluminous infrared galaxy IRAS 10190+1322
J. Gracia-Carpio, P. Planesas, L. Colina
We present the results of high resolution mapping of the CO(1-0) and CO(2-1) emission of the ultraluminous infrared galaxy (ULIRG) IRAS 10190+1322, with the IRAM interferometer, do…
Dense molecular gas in a sample of LIRGs and ULIRGs: The low-redshift connection to the huge high-redshift starbursts and AGNs
J. Gracia-Carpio, S. Garcia-Burillo, P. Planesas
The sample of nearby LIRGs and ULIRGs for which dense molecular gas tracers have been measured is building up, allowing for the study of the physical and chemical properties of the…
Detection of HNC and tentative detection of CN at z=3.9
M. Guelin, P. Salome, R. Neri +8
Molecular line emission from high-redshift galaxies holds great promise for the study of galaxy formation and evolution. The weak signals can only be detected with the largest mm-w…
Probing the feeding and feedback of AGN through molecular line maps
S. Garcia-Burillo, F. Combes, A. Usero +1
Current mm-interferometers can provide a complete view of the distribution and kinematics of molecular gas in the circumnuclear disks of nearby galaxies. High-resolution CO maps ar…
A New Probe of Dense Gas at High Redshift: Detection of HCO+(5-4) Line Emission in APM 08279+5255
S. Garcia-Burillo, J. Gracia-Carpio, M. Guelin +6
We report the detection of HCO+(5-4) emission from the Broad Absorption Line (BAL) quasar APM08279+5255 at z=3.911 based on observations conducted at the IRAM Plateau de Bure inter…
Extragalactic chemistry of molecular gas: lessons from the local universe
S. Garcia-Burillo, A. Fuente, J. Martin-Pintado +3
Observational constraints provided by high resolution and high sensitivity observations of external galaxies made in the millimeter and submillimeter range have started to put on a…
Is HCN a True Tracer of Dense Molecular Gas in LIRGs and ULIRGs?
J. Gracia-Carpio, S. Garcia-Burillo, P. Planesas +1
We present the results of the first HCO+ survey probing the dense molecular gas content of a sample of 16 luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs). Previous…
