We present the rationale for and the observational description of ASPECS: the ALMA SPECtroscopic Survey in the Hubble Ultra-Deep Field (UDF), the cosmological deep field that has the deepest multi-wavelength data available. Our overarching goal is to obtain an unbiased census of molecular gas and dust continuum emission in high-redshift (z>0.5) galaxies.(More)

We present the redshift distribution of the SHADES galaxy population based on the rest-frame radio-mm-FIR colours of 120 robustly detected 850μm sources in the Lockman Hole East (LH) and Subaru XMM-Newton Deep Field (SXDF). The redshift distribution derived from the full SED information is shown to be narrower than that determined from the radio–submm(More)
We report on interferometric observations of the CO J=1–0 and J=3–2 line emission from the controversial QSO/galaxy pair HE0450–2958. The detected CO J=1–0 line emission is found associated with the disturbed companion galaxy not the luminous QSO, and implies Mgal(H2) ∼ (1 − 2) × 10M⊙, which is > ∼ 30% of the dynamical mass in its ∼ 11 kpc×6 kpc CO-luminous(More)
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of the [C ii] 158μm fine structure line and dust continuum emission from the host galaxies of five redshift 6 quasars. We also report complementary observations of 250 GHz dust continuum and CO (6–5) line emission from the z = 6.00 quasar SDSS J231038.88+185519.7 using the IRAM(More)
We make use of deep 1.2 mm continuum observations (12.7 μJy beam rms) of a 1 arcmin region in the Hubble Ultra Deep Field to probe dust-enshrouded star formation from 330 Lyman-break galaxies spanning the redshift range z=2–10 (to ∼2–3 Me yr at 1σ over the entire range). Given the depth and area of ASPECS, we would expect to tentatively detect 35(More)

We explore the relationship between gas, dust and star formation in a sample of 12 ultra-luminous infrared galaxies (ULIRGs) at high redshift compared to a similar sample of local galaxies. We present new CO observations and/or Spitzer mid-IR spectroscopy for 6 70μm-selected galaxies at z ∼ 1 in order to quantify the properties of the molecular gas(More)
We present the redshift distribution of the Submillimetre Common-User Bolometer Array (SCUBA) Half Degree Survey (SHADES) galaxy population based on the rest-frame radio– mm–far-infrared (FIR) colours of 120 robustly detected 850 μm sources in the Lockman Hole East (LH) and Subaru XMM–Newton Deep Field (SXDF).
