Aims:We analyze the distribution of the interstellar matter in the environs of the H ii region Gum 31, excited by the open cluster NGC 3324, located in the...
The Episodic Dust-Maker WR:125 - Part Two - Spectroscopy and Photometry during Infrared Maximum
During 1992-93 the infrared flux from the Wolf-Rayet star WR 125, which formed a dust shell in 1990-91, reached a maximum. This is attributed to the continuous...
The episodic star formation history of the Carina dwarf spheroidal galaxy
We present deep photometry of the Carina dwarf spheroidal galaxy in the B and V filters from CTIO/MOSAIC out to and beyond the tidal radius of rell ≈ 0.48...

The ESO Diffuse Interstellar Bands Large Exploration Survey (EDIBLES) . I. Project description, survey sample, and quality assessment
The carriers of the diffuse interstellar bands (DIBs) are largely unidentified molecules ubiquitously present in the interstellar medium (ISM). After decades of...
The ESPRESSO Redshift Drift Experiment: I. High-resolution spectra of the Lyman-α forest of QSO J052915.80-435152.0
Context. The measurement of the tiny temporal evolution in the redshift of distant objects, the redshift drift, is a powerful probe of universal expansion and...
The ESPRESSO transmission spectrum of HD189733 b: Extracting the planetary sodium and lithium signatures amid stellar contamination
Context. While transmission spectroscopy has allowed us to detect many atomic and molecular species in exoplanet atmospheres, the improvement in resolution and...
The Establishment of the Standard Cosmological Model Through Observations
Over the last decades, observations with increasing quality have revolutionized our understanding of the general properties of the Universe. Questions posed for...
