Evolutionary synthesis of galaxies at high spectral resolution with the code PEGASE-HR. Metallicity and age tracers
We present PEGASE-HR, a new stellar population synthesis program generating high resolution spectra (R = 10 000) over the optical range λλ = 400-680 nm. It links the spectro-photometric model ofExpand

A SCUBA survey of the NGC 2068/2071 protoclusters
We report the results of a submillimeter dust continuum survey of the protoclusters NGC 2068 and NGC 2071 in Orion B carried out at 850 m and 450 m with SCUBA on JCMT. The mapped region is32 0 18 0Expand

CO Depletion and Deuterium Fractionation in Prestellar Cores
We report the detection of D2CO in a sample of starless dense cores, in which we previously measured the degree of CO depletion. The deuterium fractionation is found to be extremely high,Expand

Multiple protostellar systems: I. A deep near infrared survey of Taurus and Ophiuchus protostellar objects
We performed a deep infrared imaging survey of 63 embedded young stellar objects (YSOs) located in the Taurus and Ophiuchus clouds to search for companions. The sample includes Class I and flatExpand

12 CO(1{0) observations of NGC 4848: A Coma galaxy after stripping
We study the molecular gas content and distribution in the Coma cluster spiral galaxy NGC 4848 which is Hi decient and where the remaining atomic gas is on one side of the galaxy, presumably becauseExpand

The degree of CO depletion in pre-stellar cores ?
We present new results on CO depletion in a sample of nearby pre-stellar cores, based on observations of the millimeter C 17 O and C 18 O lines and the 1.3 mm dust emission with the IRAM 30 mExpand

The initial conditions of isolated star formation – VII. Spitzer mapping of pre-stellar cores
We have retrieved Spitzer archive data of pre-stellar cores taken with the Multiband Imaging Photometer for Spitzer (MIPS) at a wavelength of 160 μm. Seventeen images, containing 18 cores, wereExpand

New CO observations and simulations of the NGC 4438/NGC 4435 system
NGC 4438 is a highly perturbed spiral with a stellar tidal tail and extraplanar molecular gas, now very HI deficient, crossing the center of the Virgo cluster at high speed. Various authors haveExpand
