The study of high-redshift objects is rapidly developing, allowing to build the star formation history of the Universe. Since most of the flux from starbursts comes out in the FIR region, the submm and mm are privileged domains for the exploration at high z. I review the recent work on galaxies at high redshift in this wavelength region, for the continuum as well as for the line detection (dust and molecular gas). Perspectives are discussed to detect early objects (maybe protogalaxies) with the… 
Gravitational Lensing at Millimeter Wavelengths
The study of gas and dust at high redshift gives an unbiased view of star formation in obscured objects as well as the chemical evolution history of galaxies. With today’s millimeter and
The promise of interferometry in the mm range: ALMA
The Atacama Large Millimeter Array (ALMA), a world-wide project (64x12m-dishes operating from 84 to 720 GHz, to be completed by 2011) will represent a jump of almost two orders of magnitude in

Probing isotopic ratios at z = 0.89 : molecular line absorption in front of the quasar PKS 1830-211
With the Plateau de Bure interferometer, we have measured the C, N, O and S isotopic abundance ratios in the arm of a spiral galaxy with a redshift of 0.89. The galaxy is seen face-on according to
High resolution observations of a starburst at z = 0.223: resolved CO(1–0) structure
We present the results of CO(1-0) emission mapping with the IRAM interferometer, at \sim 1 arcsec, resolution, of the z=0.223 ultra-luminous starburst IRAS 11582+3020. This galaxy was selected from

Finding protoquasars at high resdshifts
Phenomenological and theoretical arguments suggest that the progenitors of quasars form at high redshifts (z≥10). Searches for protoquasars may best be undertaken in the infrared or millimeter
Detection of molecular gas in the quasar BR1202 – 0725 at redshift z = 4.69
TLDR
The detection of CO emission from the radio-quiet quasar BR1202 – 0725 is reported and it is estimated that almost 1011 solar masses of molecular hydrogen are associated with the quasar; this is comparable to the stellar mass of a present-day luminous galaxy.

Molecular gas and dust around a radio-quiet quasar at redshift 4.69
TLDR
The detection of carbon monoxide confirms the presence of a large mass of molecular gas in one of the most distant galaxies known, and shows that conditions conducive to huge bursts of star formation existed in the very early Universe.
The optically dark side of galaxy formation
Deep optical surveys, probe the rest-frame ultraviolet luminosities of high-redshift galaxies. They can therefore be used to infer star formation rates, under assumptions about young stellar
High-redshift star formation in the Hubble Deep Field revealed by a submillimetre-wavelength survey
In the local Universe, most galaxies are dominated by stars, with less than ten per cent of their visible mass in the form of gas. Determining when most of these stars formed is one of the central

Determination of the epoch-dependent star formation rate of field galaxies is one of the principal goals of observational cosmology. Recently, Hughes et al., using the Submillimeter Common-User
Dense molecular clouds and the ARP 220 starburst
The IRAM 30 m telescope has been used to detect CS(3-2) and (C-13)O(2-1) emission from Arp 220, the prototype infrared luminous galaxy. The CS luminosity of Arp 220 is half the (C-12)O luminosity of
THE MOLECULAR INTERSTELLAR MEDIUM IN ULTRALUMINOUS INFRARED GALAXIES
We present observations with the IRAM 30 m telescope of CO in a large sample of ultraluminous IR galaxies out to redshift z = 0.3. Most of the ultraluminous galaxies in this sample are interacting,
