We utilize the concept of sparsity or compressibility to develop an new generation of inversion codes for the Stokes parameters. The inversion code uses...
New near-infrared JHKs light-curve templates for RR Lyrae variables
We provide homogeneous optical (UBVRI) and near-infrared (NIR, JHK) time series photometry for 254 cluster (ω Cen, M 4) and field RR Lyrae (RRL) variables. We...
New observations of asteroid (175706) 1996 FG3, primary target of the ESA Marco Polo-R mission
Context. Near-Earth asteroid (175706) 1996 FG3 is the primary target of the ESA Marco Polo-R mission, which was selected for the assessment study phase of ESA...
New Radio Observations of Anomalous Microwave Emission in the H II Region RCW175
We have observed the H II region RCW175 with the 64 m Parkes telescope at 8.4 GHz and 13.5 GHz in total intensity, and at 21.5 GHz in both total intensity and...
New Teff and [Fe/H] spectroscopic calibration for FGK dwarfs and GK giants
Context. The ever-growing number of large spectroscopic survey programs has increased the importance of fast and reliable methods with which to determine...
nIFTy galaxy cluster simulations - I. Dark matter and non-radiative models
We have simulated the formation of a galaxy cluster in a Λ cold dark matter universe using 13 different codes modelling only gravity and non-radiative...
nIFTy galaxy cluster simulations - IV. Quantifying the influence of baryons on halo properties
Building on the initial results of the nIFTy simulated galaxy cluster comparison, we compare and contrast the impact of baryonic physics with a single massive...
NIHAO-LG: the uniqueness of Local Group dwarf galaxies
Recent observational and theoretical studies of the Local Group (LG) dwarf galaxies have highlighted their unique star-formation history, stellar metallicity...
No swan song for Sun-as-a-star helioseismology: Performances of the Solar-SONG prototype for individual mode characterisation
The GOLF instrument on board SoHO has been in operation for almost 25 years, but the ageing of the instrument has now strongly affected its performance...
