The Near-Infrared Spectrometer and Photometer (NISP) on board the Euclid satellite provides multiband photometry R>=450 slitless grism spectroscopy in 950-2020nm wavelength range. In this reference article we illuminate background of NISP's functional calibration requirements, describe instrument's integral components, provide all its key properties. We also sketch processes needed to understand how NISP operates is calibrated, technical potentials limitations. Links articles providing more...
Abstract We examine the morphological and kinematical properties of SPT-2147, a strongly lensed, massive, dusty, star-forming galaxy at z = 3.762. Combining data from JWST, HST, ALMA, we study galaxy’s stellar emission, dust continuum gas properties. The imaging reveals central bar structure in stars embedded within an extended disc with spiral arm-like feature. kinematics confirm presence regularly rotating disc. Dynamical modeling yields dynamical mass, Mdyn (9.7 ± 2.0) × 1010 M⊙, maximum...
We analyse the molecular and atomic emission lines of 71 bright Herschel-selected galaxies between redshifts 1.4 to 4.6 detected by Atacama Large Millimetre/submillimetre Array. These include a total 156 CO, [C I], H2O lines. For 46 galaxies, we detect two transitions CO lines, for these find gas properties similar those other dusty star-forming galaxy (DSFG) samples. A comparison photo-dissociation models suggests that most have interstellar medium conditions as local infrared-luminous...
We present spectroscopic measurements for 71 galaxies associated with 62 of the brightest high-redshift submillimeter sources from Southern fields Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS), while targeting 85 which resolved into 142. have obtained robust redshift all using 12-m Array and an efficient tuning ALMA to optimise its use as a hunter, 73 per cent having identification. Nine these identifications also rely on observations Atacama Compact Array. The redshifts span...
Using the IRAM NOrthern Extended Millimetre Array (NOEMA), we conducted a Large Programme ( z -GAL) to measure redshifts for 126 bright galaxies detected in Herschel Astrophysical Area Survey (H-ATLAS), HerMES Mode (HeLMS), and Stripe 82 (HerS) Survey. We report reliable spectroscopic total of 124 -selected galaxies. The are estimated from scans 3 2-mm bands (and, one source, 1-mm band), covering up 31 GHz each band, based on detection at least two emission lines. Together with Pilot...
We present 101 and 151 GHz ALMA continuum images for 85 fields selected from Herschel observations that have 500 micron flux densities >80 mJy 250-500 colours consistent with z > 2, most of which are expected to be gravitationally lensed or hyperluminous infrared galaxies. Approximately half the sources were resolved into multiple sources, but 11 15 brightest correspond individual sources. For 37 containing either a single source spectroscopic redshift two same redshift, we examined colour...
We have carried out the first spatially-resolved investigation of multi-phase interstellar medium (ISM) at high redshift, using z=4.24 strongly-lensed sub-millimetre galaxy H-ATLASJ142413.9+022303 (ID141). present high-resolution (down to ~350 pc) ALMA observations in dust continuum emission and CO(7-6), H_2O (2_{1,1} - 2_{0,2}), CI(1-0) CI(2-1) lines, latter two allowing us spatially resolve cool phase ISM for time. Our modelling kinematics reveals that system appears be dominated by a...
The z -GAL survey observed 137 bright Herschel -selected targets with the IRAM Northern Extended Millimeter Array, aim to measure their redshift and study properties. Several of them have been resolved into multiple sources. Consequently, robust spectroscopic redshifts measured for 165 individual galaxies in range 0.8 < 6.5. In this paper we analyse millimetre spectra sources, using both continuum line emission derive physical At least two spectral lines are detected each source,...

Our aim is to quantify the impact of systematic effects on inference cosmological parameters from cosmic shear. We present an end-to-end approach that introduces sources bias in a modelled weak lensing survey galaxy-by-galaxy level. Residual biases are propagated through pipeline galaxy properties (one end) shear power spectra and parameter estimates (the other end), how imperfect knowledge changes maximum likelihood values dark energy parameters. correction for charge transfer inefficiency...
ABSTRACT We have carried out Hubble Space Telescope (HST) snapshot observations at 1.1 μm of 281 candidate strongly lensed galaxies identified in the wide-area extragalactic surveys conducted with Herschel Observatory. Our candidates comprise systems flux densities $500\, \mu$m, S500 ≥ 80 mJy. model and subtract surface brightness distribution for 130 systems, where we identify a foreground lens candidate. After combining visual inspection, archival high-resolution observations, subtraction,...
