TL;DR: In this paper, a near-infrared imaging survey was conducted at the 3.5m telescope of the Calar Alto Spanish-German Astronomical Center (CAHA), covering two separated fields centered on the HFDN and the Groth field, with a total combined area of 0.27$deg$^{2}$ to a depth of $K\sim19$ ($3\sigma$,Vega).

TL;DR: In this paper, Johnson B CCD photometry for the whole sample of galaxies of the UCM Survey Lists I and II was presented, and the new colour information was combined to search for clues on the properties of the galaxies, mainly by comparing our sample with other surveys.

TL;DR: In this paper, the authors used panchromatic images of Malin 1 to constrain the stellar populations and the history of this iconic example among giant LSBGs, and found that the surface brightness and color profiles can be reproduced by a long and quiet star-formation history due to the low surface density; no significant event such as a collision, is necessary.

TL;DR: The recent spatial and temporal coincidence of the blazar TXS 0506+056 with the IceCube-detected neutrino event IC-170922A has opened up a realm of multimessenger astronomy with blazar jets as a plausible site of cosmic-ray acceleration.

TL;DR: In this paper, the authors provide aperture corrections for emission lines in a sample of spiral galaxies from the Calar Alto Legacy Integral Field Area Survey (CALIFA) database, and compute median growth curves of Halpha, Halpha/Hbeta, O3N2 and N2 up to 2.5R_50 and 1.5 disk R_eff.
