Euclid. I. Overview of the Euclid mission
/ Euclid Collaboration
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. [...]

Euclid. IV. The NISP Calibration Unit
/ Euclid Collaboration
The near-infrared calibration unit (NI-CU) on board Euclid's Near-Infrared Spectrometer and Photometer (NISP) is the first astronomical calibration lamp based on light-emitting diodes (LEDs) to be operated in space. [...]

Sloan Digital Sky Survey IV: Mapping the Milky Way, Nearby Galaxies and the Distant Universe
/ Blanton, Michael R. (Stanford U., Phys. Dept.) ; Bershady, Matthew A. (Wisconsin U., Madison, Astron.) ; Abolfathi, Bela ; Albareti, Franco D. (Madrid, Autonoma U. ; Madrid, IFT) ; Allende Prieto, Carlos ; Almeida, Andres ; Alonso-García, Javier ; Anders, Friedrich (Potsdam, Astrophys. Inst.) ; Anderson, Scott F. (LLNL, Livermore) ; Andrews, Brett et al.
We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratio in the near-infrared.

We present constraints on the parameters of the $\Lambda$CDM cosmological model in the presence of massive neutrinos, using the one-dimensional Ly$\alpha$ forest power spectrum obtained with the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey (SDSS) by Palanque-Delabrouille et al. (2013), complemented by additional cosmological probes. [...]

AGAPEROS : Searches for microlensing in the LMC with the Pixel Method; 2, Selection of possible microlensing events
/ Melchior, A.L. (Queen Mary, U. of London ; College de France) ; Afonso, C (CEA, DSM, Saclay ; DAPNIA, Saclay) ; Ansari, R (Orsay, LAL) ; Aubourg, E. (CEA, DSM, Saclay ; DAPNIA, Saclay) ; Baillon, P. (CERN) ; Bareyre, P. (CEA, DSM, Saclay ; DAPNIA, Saclay) ; Bauer, F. (CEA, DSM, Saclay ; DAPNIA, Saclay) ; Beaulieu, J.-Ph. (Paris, Inst. Astrophys.) ; Bouquet, A. (College de France) ; Brehin, S. (CEA, DSM, Saclay ; DAPNIA, Saclay) et al.
We apply the pixel method of analysis (sometimes called ``pixel lensing'') to a small subset of the EROS-1 microlensing observations of the bar of the Large Magellanic Cloud (LMC). The pixel method is designed to find microlensing events of unresolved source stars and had heretofore been applied only to M31 where essentially all sources are unresolved. [...]

AGAPEROS : Searches for microlensing in the LMC with the Pixel Method; 1, Data treatment and pixel light curves production
/ Melchior, A.-L. (Queen Mary, U. of London ; College de France ; Fermilab) ; Afonso, C. (DAPNIA, Saclay) ; Ansari, R. (Orsay, LAL) ; Aubourg, E. (DAPNIA, Saclay) ; Baillon, P. (CERN) ; Bareyre, P. (DAPNIA, Saclay) ; Bauer, F. (DAPNIA, Saclay) ; Beaulieu, J.-Ph. (Paris, Inst. Astrophys.) ; Bouquet, A. (College de France) ; Brehin, S. (DAPNIA, Saclay) et al.
The presence and abundance of MAssive Compact Halo Objects (MACHOs) towards the Large Magellanic Cloud (LMC) can be studied with microlensing searches. The 10 events detected by the EROS and MACHO groups suggest that objects with 0.5 Mo could fill 50% of the dark halo. [...]
