Radio monitoring of NLS1 galaxies: The Next Generation

In this talk I give a short overview of radio monitoring of NLS1 galaxies so far, and then focus on the possibilities offered by the new triple-band receiver (3BR) that will be installed at Metsahovi Radio Observatory in late 2025. The receiver is expected to be operational during 2026. The three frequencies 22, 43, and 86 GHz can be used simultaneously to produce a high radio frequency spectrum, and polarization capability is included. The new receiver enables an order of magnitude increase in sensitivity compared to the current system, therefore enhancing the ongoing NLS1 monitoring campaign at Metsahovi in many significant ways. Finally, I present examples of work so far done plus how to exploit the forthcoming improvements
