TL;DR: The first Event Horizon Telescope (EHT) observations of Sagittarius A* (Sgr A*), the Galactic center source associated with a supermassive black hole, were conducted in 2017 using a global interferometric array of eight telescopes operating at a wavelength of 1.3 mm as mentioned in this paper .

TL;DR: In this article, the authors exploit the deep and extended far-IR data sets (at 70, 100 and 160 μm) of the GPS PACS Evolutionary Probe (PEP) Survey, in combination with the Herschel Multi-tiered Extragalactic Survey data at 250, 350 and 500 μm, to derive the evolution of the rest-frame 35-, 60-, 90- and total infrared luminosity functions (LFs) up to z ∼ 4.

TL;DR: In this paper, the authors studied the evolution of the dust temperature of galaxies in the SFR−M∗ plane up to z ~ 2 using far-infrared and submillimetre observations from the Herschel Space Observatory taken as part of the PACS Evolutionary Probe (PEP) and Herschel Multi-tiered Extragalactic Survey (HerMES) guaranteed time key programmes.

TL;DR: In this paper, the authors study the evolution of the dust temperatures of galaxies in the SFR-M* plane up to z~2 using observations from the Herschel Space Observatory.

TL;DR: In this article, the spectral energy distribution (SED) and dust temperature of galaxies have strongly evolved since z~2.5, which may either result from stronger broad emission lines or warm dust continuum heated by a hidden AGN.
