A compact multi-planet system transiting HIP 29442 (TOI-469) discovered by TESS and ESPRESSO. Radial velocities lead to the detection of transits with low signal-to-noise ratio
M. Damasso, J. Rodrigues, A. Castro-González +52
We followed-up with ESPRESSO the K0V star HIP 29442 (TOI-469), already known to host a validated sub-Neptune companion TOI-469.01. We aim to verify the planetary nature of TOI-469.…
An unusually low-density super-Earth transiting the bright early-type M-dwarf GJ 1018 (TOI-244)
A. Castro-González, O. D. S. Demangeon, J. Lillo-Box +34
Small planets located at the lower mode of the bimodal radius distribution are generally assumed to be composed of iron and silicates in a proportion similar to that of the Earth.…
Fundamental cosmology from ANDES precision spectroscopy
C. M. J. Marques, C. J. A. P. Martins, C. S. Alves
Fundamental cosmology observations, such as the detection of the redshift drift and tests of the universality of physical laws, are key science and design drivers of the ArmazoNes…
Quantitative constraints on modified gravity paradigms
S. R. Pinto, A. M. Cabral, C. J. A. P. Martins
We use low-redshift background cosmology data to place quantitative constraints on three separate modified gravity models, each of which aims to explain the low-redshift accelerati…
Spectroscopy of QUBRICS quasar candidates: 1672 new redshifts and a Golden Sample for the Sandage Test of the Redshift Drift
Stefano Cristiani, Matteo Porru, Francesco Guarneri +10
The QUBRICS (QUasars as BRIght beacons for Cosmology in the Southern hemisphere) survey aims at constructing a sample of the brightest quasars with z>~2.5, observable with faciliti…
Cosmological evolution of Witten superconducting string networks
I. Yu. Rybak, C. J. A. P. Martins, Patrick Peter +1
We consider the evolution of current-carrying cosmic string networks described by the charge-velocity-dependent one scale (CVOS) model beyond the linear equation of state regime, s…
