The performance of the NIKA2 camera at the IRAM 30-m telescope have been assessed using a reference data set including observations acquired between January 2017 and February 2018. This data set consists of a large amount of observations of primary and secondary calibrators and faint sources, which span the whole range of observing elevations and atmospheric conditions encountered at the IRAM 30-m ...

NIKA2 has been permanently installed at the IRAM Pico Veleta 30m telescope since October 2015. After the first commissioning campaigns, NIKA2 is now open to the international community and has been used in many scientific observing pools. Although invisible to the final user, the complexity of the instrument requires a lot of careful work to get everything ready before each pool, starting from the ... Plus

I will describe in general the NIKA2 instrument. I will then focus on some possible points for improvements. For example: new dichroic, new 1mm arrays (developed at Néel), 1GHz electronics (LPSC), potential telescope upgrade (IRAM).

With its large FOV and high sensitivity, NIKA2 is a high mapping speed instrument, uniquely suited for deep surveys. During commissioning, we had the opportunity to observe faint and moderately faint sources with NIKA2. This talk will summarize the latest developments on the NIKA2 data reduction pipeline and show its first application to small deep fields and source counting.

Most of the people attending the conference have already an experience with NIKA2 observations and some of its subtleties. The NIKA2 observing sessions are organized in pools, a shared risk way of scheduling projects according to their priorities, and weather and stability requests, in order to ensure that everyone gets the best of their data. As NIKA2 reaches its second year of science operatio ... Plus

Pulsars are fascinating astrophysical objects that enable a variety of experiments usually with unrivalled precision. For example, pulsars have been used to test the equation-of-state of ultra-dense matter, or General Relativity up to the highest precision to date. However, although we have been very successful using pulsars as astronomical tools, we still do not fully understand their radio emiss ... Plus
