The clustering of the SDSS-IV extended baryon oscillation spectroscopic survey DR16 luminous red galaxy and emission-line galaxy samples: cosmic distance and structure growth measurements using multiple tracers in configuration space

Jean-Paul Richard Kneib, Cheng Zhao, Johan Comparat, Anand Stéphane Raichoor, Yuting Wang, Amélie Tamone

We perform a multitracer analysis using the complete Sloan Digital Sky Survey IV (SDSS-IV) extended Baryon Oscillation Spectroscopic Survey (eBOSS) DR16 luminous red galaxy (LRG) and the DR16 emission-line galaxy (ELG) samples in the configuration space, a ...

The formation of the Milky Way halo and its dwarf satellites; a NLTE-1D abundance analysis

Pascale Jablonka, Pierre North

We present a homogeneous set of accurate atmospheric parameters for a complete sample of very and extremely metal-poor stars in the dwarf spheroidal galaxies (dSphs) Sculptor, Ursa Minor, Sextans, Fornax, Botes I, Ursa Major II, and Leo IV. We also deliver ...

Constraining the production of cosmic rays by pulsars

Mikhail Ivanov

One of the possible sources of hadronic cosmic rays (CRs) are newborn pulsars. If this is indeed the case, they should feature diffusive gamma-ray halos produced by interactions of CRs with interstellar gas. In this paper we try to identify extended gamma- ...

Searches For High-Energy Neutrino Emission In The Galaxy With The Combined Icecube-Amanda Detector

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We report on searches for neutrino sources at energies above 200 GeV in the Northern sky of the Galactic plane, using the data collected by the South Pole neutrino telescope, IceCube, and AMANDA. The Galactic region considered in this work includes the loc ...

Searches For Periodic Neutrino Emission From Binary Systems With 22 And 40 Strings Of Icecube

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

In this paper, we present the results of searches for periodic neutrino emission from a catalog of binary systems. Such modulation, observed in the photon flux, would be caused by the geometry of these systems. In the analysis, the period is fixed by these ...

Red giants in open clusters - XIV. Mean radial velocities for 1309 stars and 166 open clusters

Jean-Claude Mermilliod

Context. Radial velocities have proved to be an efficient method for membership determination if there are at least 2 or 3 red giants in a cluster. They are necessary for galactic studies, but are still missing for many open clusters. ...

Discovery of kHz quasi-periodic oscillations in the Z source Cygnus X-2

Demetri Psaltis

During observations with the Rossi X-Ray Timing Explorer from 1997 June 31 to July 3 we discovered two simultaneous kHz quasi-periodic oscillations (QPOs) near 500 and 860 Hz in the low-mass X-ray binary and Z source Cygnus X-2. In the X-ray color-color di ...
