The HARPS search for southern extra-solar planets. XLVI: 12 super-Earths around the solar type stars HD39194, HD93385, HD96700, HD154088, and HD189567
N. Unger, D. Ségransan, D. Queloz +23
Context. We present precise radial-velocity measurements of five solar-type stars observed with the HARPS Echelle spectrograph mounted on the 3.6-m telescope in La Silla (ESO, Chil…
The XXL Survey XXV. Cosmological analysis of the C1 cluster number counts
F. Pacaud, M. Pierre, J. -B. Melin +25
Context. We present an estimation of cosmological parameters with clusters of galaxies. Aims. We constrain the , , and parameters from a stand-alone sample of X-ray c…
The HARPS search for southern extra-solar planets. XLIII. A compact system of four super-Earth planets orbiting HD 215152
J. -B. Delisle, D. Ségransan, X. Dumusque +22
We report the discovery of four super-Earth planets around HD 215152, with orbital periods of 5.76, 7.28, 10.86, and 25.2 d, and minimum masses of 1.8, 1.7, 2.8, and 2.9 M_Earth re…
The HARPS search for southern extra-solar planets. XXXVI. Eight HARPS multi-planet systems hosting 20 super-Earth and Neptune-mass companions
S. Udry, X. Dumusque, C. Lovis +21
We present radial-velocity measurement of eight stars observed with the HARPS Echelle spectrograph mounted on the 3.6-m telescope in La Silla (ESO, Chile). Data span more than ten…
The XXL Survey: IX. Optical overdensity and radio continuum analysis of a supercluster at
N. Baran, V. Smolčić, D. Milaković +18
We present observations with the Karl G. Jansky Very Large Array (VLA) at 3 GHz toward a sub-field of the XXL-North 25 deg field targeting the first supercluster discovered i…
The XXL Survey VIII: MUSE characterisation of intracluster light in a z0.53 cluster of galaxies
C. Adami, E. Pompei, T. Sadibekova +11
Within a cluster, gravitational effects can lead to the removal of stars from their parent galaxies. Gas hydrodynamical effects can additionally strip gas and dust from galaxies. T…
The XXL Survey VII: A supercluster of galaxies at z=0.43
E. Pompei, C. Adami, D. Eckert +15
The XXL Survey is the largest homogeneous and contiguous survey carried out with XMM-Newton. Covering an area of 50 square degrees distributed over two fields, it primarily investi…
The XXL Survey. II. The bright cluster sample: catalogue and luminosity function
F. Pacaud, N. Clerc, P. A. Giles +40
Context. The XXL Survey is the largest survey carried out by the XMM-Newton satellite and covers a total area of 50 square degrees distributed over two fields. It primarily aims at…
The DPOSS II distant compact group survey: the EMMI-NTT spectroscopic sample
E. Pompei, A. Iovino
This paper presents the results of the redshift survey of 138 candidate compact groups from the DPOSS II catalog (Iovino et al., 2003; de Carvalho et al. 2005), which extends the a…
