  We present the first look at the spectral and timing analysis of Narrow-Line
Seyfert 1 Galaxies (NLS1s) with the extended ROentgen Survey with an Imaging
Telescope Array (eROSITA) on board the Spectrum-Roentgen-Gamma (SRG) mission.
The sample of about 1,200 NLS1s was obtained via cross-match of the first
eROSITA All-Sky Survey (eRASS1) catalogue with the catalogue of
spectroscopically selected NLS1s from the Sloan Digital Sky Survey (SDSS) DR12
by Rakshit et al. [ApJS, 229, 39 (2017)]. The X-ray spectral analysis is based
on a simple power-law fit. The photon index distribution has a mean value of
about 2.81+-0.03, as expected from previous X-ray studies of NLS1s.
Interestingly, it is positively skewed, and about 10 percent of the sources are
located in the super-soft tail of photon indices larger than 4. These sources
are of further interest as their source counts run into the X-ray background at
values at around 1 keV. We argue that ionised outflows have been detected by
eROSITA and may account for some of the extreme spectral steepness, which is
supported by correlations found between the photon index and optical outflows
parameters. We analysed the intrinsic X-ray variability of the eRASS1 to eRASS3
light curves of the sample but do not find significant variability neither
during the individual survey scans nor between them.
