We present intensive optical, infrared, and radio monitoring observations of the BL Lac object OJ 287, taken between the years 1993-1998. Two large optical...
Intracluster light at the Frontier - II. The Frontier Fields Clusters
Multiwavelength deep observations are a key tool to understand the origin of the diffuse light in clusters of galaxies: the intracluster light (ICL). For this...
The ultra-deep multiwavelength Hubble Space Telescope Frontier Fields coverage of the Abell Cluster 2744 is used to derive the stellar population properties of...
Intracluster light: a luminous tracer for dark matter in clusters of galaxies
The bulk of stars in galaxy clusters are confined within their constituent galaxies. Those stars do not trace the extended distribution of dark matter well as...
Introducing the LBT Imaging of Galactic Halos and Tidal Structures (LIGHTS) survey. A preview of the low surface brightness Universe to be unveiled by LSST
We present the first results of the LBT Imaging of Galaxy Haloes and Tidal Structures (LIGHTS) survey. LIGHTS is an ongoing observational campaign with the 2 ×...
Introduction of MuSCAT for exoplanet studies and its initial results
NASA's Kepler mission has made a revolution in discovering a large number of transiting exoplanets. Moreover K2, TESS, and PLATO will provide more transiting...
As the present study was progressing, we started a campaign of spectroscopic follow-up of the Hα emitters detected by IPHAS. Accordingly a dozen candidate...
IR photometry of Alpha Per low-mass members (Lodieu+, 2005)
Optical detections in five different fields of view (A, C, E, K, and L) are matched with the near-infrared detections described in this paper. The central...
Dwarf galaxies in the Local Group allow to study in great detail the physical mechanisms responsible for the formation and evolution of galaxies. In fact, their...
