Among the irregular satellites orbiting Jupiter, the Himalia family is characterized by a high velocity dispersion dv of several hundred m s-1 among its members, inconsistent with a collisional origin. Efforts to account for this through internecine gravitational interactions do not readily reproduce this feature. Here, we revisit the problem in the context of recent cosmogonical models, where the
More than 50 irregular satellites revolve around Jupiter and more than 30 around Saturn. There, at least three collisional families were identified. Among these, the Himalia family of prograde irregular moons at Jupiter is characterised by a velocity dispersion of several hundred m/s, inconsistent with a collisional origin (Nesvorný et al., 2003). Here we investigate whether the dispersion could s
We characterize the selection function of RAdial Velocity Experiment (RAVE) using 2 Micron All Sky Survey (2MASS) as our underlying population, which we assume represents all stars that could have potentially been observed.We evaluate the completeness fraction as a function of position, magnitude and colour in two ways: first, on a field-by-field basis, and second, in equal-size areas on the sky.
Året är 2053 och den svenska regeringen har just invigt museet FOSSIL och dess första utställning ’Carbon Ruins’. År 2045 uppnådde Sverige nettonollutsläpp av växthusgaser, och blev därmed det första landet i världen att lämna den fossila tidsåldern (1849 - 2049). Två hundra år som förde med sig en otrolig välståndsökning, men också oljerelaterade konflikter och en klimatkatastrof som allvarligt hIt is 2053. The Swedish government has just opened its landmark museum FOSSIL with its first exhibition Carbon Ruins. The exhibition and its grand opening is a celebration of the fact that global net-zero emissions of carbon dioxide were reached in 2050. Sweden, in line with its 2017 targets, reached net-zero emissions of greenhouse gases already in 2045, being the first country in the world to st
Context. The ESA Gaia mission provides a unique time-domain survey for more than 1.6 billion sources with G ≲ 21 mag. Aims. We showcase stellar variability in the Galactic colour-absolute magnitude diagram (CaMD). We focus on pulsating, eruptive, and cataclysmic variables, as well as on stars that exhibit variability that is due to rotation and eclipses. Methods. We describe the locations of var
Mutations are not identified in ~5% of hemophilia A and 10-35% of type 1 VWD patients. The bleeding tendency also varies among patients carrying the same causative mutation, potentially indicating variants in additional genes modifying the phenotype that cannot be identified by routine single-gene analysis. The F8, F9 and VWF genes were analyzed in parallel using an AmpliSeq strategy and Ion Torre
The effect of napping versus wakefulness was studied on primed and repeated Remote Associate Tests (RATs) and on divergent creativity tests. The participants were 42 students from the USA, studying international courses at a Swedish university. The hypotheses for the RATs were (1), when the correct answers were primed before the nap, the RAT should be solved better for those who entered REM sleep,
The future opportunities for high-density QCD studies with ion and proton beams at the LHC are presented. Four major scientific goals are identified: the characterisation of the macroscopic long wavelength Quark-Gluon Plasma (QGP) properties with unprecedented precision, the investigation of the microscopic parton dynamics underlying QGP properties, the development of a unified picture of particle
This document describes the first proof-of-concept version of the PYTHIA7 program. PYTHIA7 is a complete re-write of the PYTHIA program in C++. It is mainly intended to be a replacement for the `Lund' family of event generators, but is also a framework with a structure suitable for implementing any event generator model. In this document, the structure of the program is presented both from the use
A model for total cross sections with virtual photons is presented. In particular γ*p and γ*γ* cross sections are considered. Our approach extends on a model for photoproduction, where the total cross section is subdivided into three distinct event classes: direct, VMD and anomalous. With increasing photon virtuality, the latter two decrease in importance. Instead Deep Inelastic Scattering dominat
