During the dawn of chemistry when the temperature of the young Universe had fallen below $\sim$4000 K, the ions of the light elements produced in Big Bang nucleosynthesis recombined in reverse order of their ionization potential. With its higher ioni

We present the upGREAT THz heterodyne arrays for far-infrared astronomy. The Low Frequency Array (LFA) is designed to cover the 1.9-2.5 THz range using 2x7-pixel waveguide-based HEB mixer arrays in a dual polarization configuration. The High Frequenc

During the embedded stage of star formation, bipolar molecular outflows and UV radiation from the protostar are important feedback processes. Our aim is to quantify the feedback, mechanical and radiative, for a large sample of low-mass sources. The o

The first heterodyne array receivers have been successfully built for ground-based telescopes and airborne observatories.In the talk we give a very quick overview of some prior heterodyne arrays. In particular, we will look at the innovations they in

It was 13 years ago, in May 2007, when the Large APEX Bolometer Camera (LABOCA) was commissioned as a facility instrument on the APEX telescope at the 5100-m-high Llano de Chajnantor. This 870-µm bolometer camera, in combination with the high effici
