This series of papers aims at understanding the formation and evolution of non-barred disc galaxies. We use the new spectro-photometric decomposition code, C2D, to separate the spectral information of bulges and discs of a statistically representative sample of galaxies from the CALIFA survey. Then, we study their stellar population properties

Context. The nuclear stellar disc (NSD) is, together with the nuclear star cluster (NSC) and the central massive black hole, one of the main components in the central parts of our Milky Way. However, until recently, only a few studies of the stellar content of the NSD have been obtained owing to extreme extinction and stellar crowding. Aims: We

The BL Lac object 1ES~2344+514 was one of the first sources to be included in the extreme high-peaked BL Lac (EHBL) family. EHBLs are characterised by a broadband spectral energy distribution featuring the synchrotron peak above $\sim 1$ keV. 1ES~2344+514 was detected in very-high-energy (VHE) gamma rays for the first time by the Whipple telescope

We report the detection of 23 OH + 1 → 0 absorption, emission, or P-Cygni-shaped lines and CO(J = 9→8) emission lines in 18 Herschel-selected z = 2-6 starburst galaxies with the Atacama Large Millimeter/submillimeter Array and the NOrthern Extended Millimeter Array, taken as part of the Gas And Dust Over cosmic Time Galaxy Survey. We find that the

The Cluster HEritage project with XMM-Newton - Mass Assembly and Thermodynamics at the Endpoint of structure formation (CHEX-MATE) is a three-mega-second Multi-Year Heritage Programme to obtain X-ray observations of a minimally-biased, signal-to-noise-limited sample of 118 galaxy clusters detected by Planck through the Sunyaev-Zeldovich effect. The

We report the discovery of two planetary systems, namely G 264-012, an M 4.0 dwarf with two terrestrial planets (M b sin i=2.50 −0.30 +0.29 M ⊕ and M c sin i=3.75 −0.47 +0.48 M ⊕), and Gl 393, a bright M 2.0 dwarf with one terrestrial planet (M b sini = 1.71 ± 0.24M ⊕). Although both stars were proposed to belong to young stellar kinematic groups
