IFU Observations of Collimated Bipolar Outflows in Wolf-Rayet Planetary Nebulae
<p><strong>IFU Observations of Collimated Bipolar Outflows in Wolf-Rayet Planetary Nebulae</strong></p> <p>A large fraction of planetary nebulae have been found to have aspherical morphologies with collimated outflows. We do not fully comprehend how these axisymmetric morphologies are formed. I recently conducted kinematic studies of a sample of Galactic planetary nebulae around Wolf-Rayet stars using integral field unit (IFU) observations collected with the ANU 2.3-m telescope. I constrained their 3D morpho-kinematic models with position-velocity (P-V) diagrams and velocity channel maps extracted from IFU observations, together with archival high-resolution imaging observations, using the kinematic modeling program SHAPE (<a href="https://arxiv.org/abs/2107.03994">arXiv:2107.03994</a>). Collimated bipolar outflows are noticeable in the P-V diagrams of many of these objects, while their main shells have elliptical morphologies based on IFU velocity channel maps and high-resolution images. Further studies are required to explore possible links between their bipolar outflows and hydrogen-deficient Wolf-Rayet central stars.</p> <p>Pitch Talk presented at <em>IAU Symposium 366: The Origin of Outflows in Evolved Stars</em> (<a href="https://iaus366.be/">iaus366.be</a>), Virtual Meeting, 1-5 November 2021</p>

Optical polarimetric observations of low-mass X-ray black hole binary MAXI J1820+070 during 2019-2021
<p>The dataset contains raw polarimetric FITS images of the low-mass X-ray black hole binary <a href="https://www.astronomerstelegram.org/?read=11399">MAXI J1820+070</a> (and surrounding field), obtained by the <a href="https://doi.org/10.3847/1538-3881/abc74f">DIPol-UF </a>optical CCD polarimeter in three (BVR) filters while mounted on the 2.56m <a href="https://www.not.iac.es">Nordic Optical Telescope</a>. The data were collected over 5 observing runs throughout 2019--2021. During each observing night, a set of calibration images were also obtained. These typically include 7 dark and 7 bias images per filter per night (sometimes more if weather conditions or instrument settings changed during observations). Bias and dark FITS files have `_bias` or `_dark` labels in their names, as well as FITS key `IMAGETYP` set to either `Bias Frame` or `Dark Frame`, respectively.</p>

Training and test data for retrievals based on MiRAC-P observations during MOSAiC
<p>The dataset consists of one netCDF file that contains the entire training and test data for the retrieval of integrated water vapour (prw) from brightness temperatures (tb) measured by the MiRAC-P (microwave radiometer for Arctic clouds, aka. LHUMPRO-243-340). A neural network retrieval has been developed to derive the prw. The trained retrieval is applied on the MiRAC-P observations gathered onboard the research vessel Polarstern during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. For the data to be specialized on Arctic conditions they are based on ERA-Interim reanalysis. An IDL-based radiative transfer model has been used to simulate brightness temperatures. The elevation angle (ele) is always 90° because the MiRAC-P performed zenith scans only throughout the MOSAiC campaign.</p>
