The companion to PSR J1622-0315, one of the most compact known redback millisecond pulsars, shows extremely low irradiation despite its short orbital period. We model this system to determine the binary parameters, combining optical observations from the New Technology Telescope in 2017 and the Nordic Optical Telescope in 2022 with the binary

Ongoing deep integral-field spectroscopy (IFS) observations of disc galaxies provide opportunities for comparison with the Milky Way (MW) to understand galaxy evolution. However, such comparisons are marred by many challenges such as selection effects, differences in observations and methodology, and proper validation of full-spectrum fitting

Extracting precise cosmology from weak lensing surveys requires modelling the non-linear matter power spectrum, which is suppressed at small scales due to baryonic feedback processes. However, hydrodynamical galaxy formation simulations make widely varying predictions for the amplitude and extent of this effect. We use measurements of Dark Energy

We study the dynamics of homogeneous and isotropic Friedmann–Lemaître–Robertson–Walker cosmological models with positive spatial curvature within the context of mimetic gravity theory by employing dynamical system techniques. Our analysis yields phase-space trajectories that describe physically relevant solutions, capturing various stages of cosmic

Michael Hoskin is the name of a scholar whose memory will remain forever linked to cultural astronomy. Professor of History of Science at the University of Cambridge, in the United Kingdom, where he first specialized in Isaac Newton and his 'Principia'. Later on, he would devoted a great deal of his efforts to the family of William Herschel, with

During the transition from the first to the second millennium, a new artistic and architectural style known as “Romanesque” emerged and developed in the Iberian Peninsula between the 11th and 13th centuries. Many resources were invested in the construction of churches and monasteries, particularly in the regions crossed by the Camino de ­Santiago
