Weighing Neutrinos with Cosmic Neutral Hydrogen
Viel, Matteo; Bull, Philip; Villaescusa-Navarro, Francisco
We investigate the signatures left by massive neutrinos on the spatial distribution of neutral hydrogen (H i) in the post-reionization era by running hydrodynamic simulations that include massive neutrinos as additional collisionless particles. We find that halos in massive/massless neutrino cosmologies host a similar amount of neutral hydrogen, a…
E-BOSS: An Extensive stellar BOw Shock Survey. II. Catalogue second release
Peri, C. S.; Benaglia, P.; Isequilla, N. L.
Context. Stellar bow shocks have been studied not only observationally, but also theoretically since the late 1980s. Only a few catalogues of them exist. The bow shocks show emission along all the electromagnetic spectrum, but they are detected more easily in infrared wavelengths. The release of new and high-quality infrared data eases the discove…
Chemical tracers of episodic accretion in low-mass protostars
Bergin, Edwin A.; Visser, Ruud; Jørgensen, Jes K.
Aims: Accretion rates in low-mass protostars can be highly variable in time. Each accretion burst is accompanied by a temporary increase in luminosity, heating up the circumstellar envelope and altering the chemical composition of the gas and dust. This paper aims to study such chemical effects and discusses the feasibility of using molecular…
The evolving relation between star formation rate and stellar mass in the VIDEO survey since z = 3
Vaccari, Mattia; Häußler, Boris; Jarvis, Matt +4 more
We investigate the star formation rate (SFR) and stellar mass, M*, relation of a star-forming (SF) galaxy (SFG) sample in the XMM-LSS field to z ∼ 3.0 using the near-infrared data from the VISTA Deep Extragalactic Observations (VIDEO) survey. Combining VIDEO with broad-band photometry, we use the SED fitting algorithm CIGALE to derive S…

The Seven Sisters DANCe. I. Empirical isochrones, luminosity, and mass functions of the Pleiades cluster
Bertin, E.; Bouy, H.; Sarro, L. M. +7 more
Context. The DANCe survey provides photometric and astrometric (position and proper motion) measurements for approximately 2 million unique sources in a region encompassing ~80 deg2 centered on the Pleiades cluster.
Aims: We aim at deriving a complete census of the Pleiades and measure the mass and luminosity functions of the clust…
Detecting primordial B-modes after Planck
Zaldarriaga, Matias; Creminelli, Paolo; López Nacir, Diana +2 more
We update the forecasts for the measurement of the tensor-to-scalar ratio r for various ground-based experiments (AdvACT, CLASS, Keck/BICEP3, Simons Array, SPT-3G), balloons (EBEX 10k and Spider) and satellites (CMBPol, COrE and LiteBIRD), taking into account the recent Planck data on polarized dust and using a component separation method. The for…

Three-dimensional Multi-probe Analysis of the Galaxy Cluster A1689
Broadhurst, Tom; Mroczkowski, Tony; Umetsu, Keiichi +7 more
We perform a three-dimensional multi-probe analysis of the rich galaxy cluster A1689, one of the most powerful known lenses on the sky, by combining improved weak-lensing data from new wide-field {{BVR}}Ci\prime z\prime Subaru/Suprime-Cam observations with strong-lensing, X-ray, and Sunyaev-Zel’dovich effect (SZE) data sets. We reconstr…
Pressure distribution of the high-redshift cluster of galaxies CL J1226.9+3332 with NIKA
Adam, R.; Benoît, A.; Catalano, A. +37 more
The thermal Sunyaev-Zel'dovich (tSZ) effect is expected to provide a low scatter mass proxy for galaxy clusters since it is directly proportional to the cluster thermal energy. The tSZ observations have proven to be a powerful tool for detecting and studying them, but high angular resolution observations are now needed to push their investigation …
