A numerical study of interactions and stellar bars
For several decades, it has been known that stellar bars in disc galaxies can be triggered by interactions, or by internal processes such as dynamical...
A peculiar galaxy appears at redshift 11: properties of a moderate-redshift interloper
In 2011 Laporte et al. reported a very high redshift galaxy candidate: a lensed J-band dropout (A2667-J1). J1 has a photometric redshift of z= 9.6-12, the...
A peculiar Of star in the Local Group galaxy IC 1613
Context. Results from the theory of radiatively driven winds are nowadays incorporated in stellar evolutionary and population synthesis models, and are used in...
A Petal of the Sunflower: Photometry of the Stellar Tidal Stream in the Halo of Messier 63 (NGC 5055)
We present deep surface photometry of a very faint, giant arc-loop feature in the halo of the nearby spiral galaxy NGC 5055 (M63) that is consistent with being...
A photometric analysis of Abell 1689: two-dimensional multistructure decomposition, morphological classification and the Fundamental Plane
We present a photometric analysis of 65 galaxies in the rich cluster Abell 1689 at z = 0.183, using the Hubble Space Telescope Advanced Camera for Surveys...
A Photometric and Kinematic Study of the Stars and Interstellar Medium in the Central 2 Kiloparsecs of NGC 3379
Hubble Space Telescope images of NGC 3379 show that the V and I luminosity profiles in the inner 13" of this E1 galaxy are represented by two different...
A photometric method to determine supermassive black hole masses
We report the discovery of a strong correlation between the shape of a bulge's light-profile and the mass of its central supermassive black hole (Mbh). We find...
A physically motivated definition for the size of galaxies in an era of ultradeep imaging
Present-day multiwavelength deep imaging surveys allow to characterize the outskirts of galaxies with unprecedented precision. Taking advantage of this...
We have carried out a pilot study for the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) ‘All-Sky’ Survey (SASSy), a wide and shallow mapping project at...
