The early days of the Sculptor dwarf spheroidal galaxy

Pascale Jablonka, Pierre North, Yves Revaz

We present the high-resolution spectroscopic study of five -3.9

Planck 2013 results. XI. All-sky model of thermal dust emission

Julien Lesgourgues, Fabio Finelli

This paper presents an all-sky model of dust emission from the Planck 353, 545, and 857 GHz, and IRAS 100 mu m data. Using a modified blackbody fit to the data we present all-sky maps of the dust optical depth, temperature, and spectral index over the 353- ...

Planck 2013 results. XIII. Galactic CO emission

Xin Chen, Julien Lesgourgues, Fabio Finelli

Rotational transition lines of CO play a major role in molecular radio astronomy as a mass tracer and in particular in the study of star formation and Galactic structure. Although a wealth of data exists for the Galactic plane and some well-known molecular ...

The Smith Cloud and its dark matter halo: survival of a Galactic disc passage

Matthew Luke Nichols

Under conservative assumptions about the Galaxy, the derived velocity of the Smith Cloud indicates that it will have undergone at least one passage of the Galactic disc. Using hydrodynamic simulations, we examine the present-day structure of the Smith Clou ...

State of the Art in Surface Reconstruction from Point Clouds

Andrea Tagliasacchi

The area of surface reconstruction has seen substantial progress in the past two decades. The traditional problem addressed by surface reconstruction is to recover the digital representation of a physical shape that has been scanned, where the scanned data ...

Cold gas in the inner regions of intermediate redshift clusters

Pascale Jablonka

Determining the nature and modes of star formation at galactic scales requires an understanding of the relationship between the gas content of a galaxy and its star formation rate. Remarkable progress has been made in understanding the conversion mechanism ...

The haloes of bright satellite galaxies in a warm dark matter universe

Alexey Boyarsky, Oleg Ruchayskiy, Jie Wang

High-resolution N-body simulations of galactic cold dark matter haloes indicate that we should expect to find a few satellite galaxies around the Milky Way whose haloes have a maximum circular velocity in excess of 40 km s-1. Yet, with the exception of the ...

Cell-based Automatic Deformation Computation by Analyzing Terrestrial LIDAR Point Clouds

Pierre-Yves Gilliéron, Bertrand Merminod, Jing Wu

This paper presents a cell-based approach for computing the deformation of a monitored object by analyzing point cloud data from terrestrial lidar. This approach can automatically generate an informative deformation description (called "deformation map") w ...

In-cloud oxalate formation in the global troposphere: A 3-D modeling study

Athanasios Nenes

Organic acids attract increasing attention as contributors to atmospheric acidity, secondary organic aerosol mass and aerosol hygroscopicity. Oxalic acid is globally the most abundant dicarboxylic acid, formed via chemical oxidation of gas-phase precursors ...

A novel tethered-sphere add-on to enhance grid turbulence

Peter Monkewitz, Richard Vonlanthen

The new turbulence generator consists of a standard uniform grid with tethered spheres attached to its nodes and is capable of producing approximately twice the turbulence energy per unit pressure drop coefficient C (p) than the same bare grid without the ...
