The Javalambre Photometric Local Universe Survey (J-PLUS) is a spectro-photometricsurvey covering about 3,000~deg 2 in its third data release (DR3), and containing about 300,000 galaxies with high quality ({} >0.8) photometric redshifts (hereafter photo- zs). We use this galaxy sample to conduct a tomographic study of the counts and redshift

T CrB is a symbiotic recurrent nova that last erupted in 1946. Given its recurrence time-scale of approximately 80 yr, the next outburst is eagerly anticipated by the astronomical community. In this work, we analyse the optical light curves of T CrB, comparing recent photometric evolution with historical data to evaluate potential predictive

Despite the immense voids and vast distances that separate stars, our cosmic neighborhood remains a dynamic stage where emerging phenomena consistently challenge our present comprehension. One of the most intriguing enigmas involves the appearance of objects originating from distant stellar systems. We provide an introduction to the realm of

Relics are massive, compact and quiescent galaxies that assembled the majority of their stars in the early Universe and lived untouched until today, completely missing any subsequent size growth caused by mergers and interactions. They provide the unique opportunity to put constraints on the first phase of mass assembly in the Universe with the

Aims. Our aim was to study the chromospheric line-of-sight (LOS) velocities during the GOES M3.2 flare (SOL2013-05-17T08:43) using simultaneous high-resolution ground-based spectroscopic data of the He I 10830 Å triplet and Ca II 8542 Å line. A filament was present in the flaring area. Methods. The observational data were acquired with the Vacuum

Writing proposals and job applications is arguably one of the most important tasks in the career of a scientist. The proposed ideas must be scientifically compelling, but how a proposal is planned, written and presented can make an enormous difference. This Perspective is the third in a series aimed at training the writing skills of professional
