The Search For Pulsar Wind Nebulae in the Very High Energy Gamma-ray Regime [PDF]
, 2010 The aim of this Thesis is to study the development of pulsar wind nebulae in the TeV regime and in doing so uncover more sources which have as yet not been observed at these wavelengths.

The Bochum Survey of the Southern Galactic Disk: IV. Multi‐Band Photometry
Astronomische Nachrichten, EarlyView.ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°‐wide stripe in the southern galactic disk from September 2010 to September 2019. These fields were observed between 21 and 407 times sim r′$$ {r}^{\prime } $$ultaneously in (8mag≲r′≲18mag$$ 8\kern0.6em \mathrm{mag}\lesssim {r}^{\prime}\lesssim 18\kern0.6em ...

Investigating Time Variability of X-Ray Absorption in Swift GRBs
The Astrophysical Journal, 2023 The existence of excess absorption in the X-ray spectra of GRBs is well known, but the primary location of the absorbing material is still uncertain. To gain more knowledge about this, we have performed a time-resolved analysis of the X-ray spectra of ...

EBHIS Local Volume Galaxy Hi Survey (LVGHIS)
Astronomische Nachrichten, EarlyView.ABSTRACT Here, we present the “Local Volume Galaxy Hi Survey” (LVGHIS). It is based on the first data release of the Milky Way portion of the Effelsberg Bonn Hi‐Survey (EBHIS). We homogeneously measured the mass and dynamics of the local volume galaxies within the radial velocity limit of |vLSR|≤600kms−1$$ \mid {v}_{\mathrm{LSR}}\mid \le 600\kern0.6em \
