title: Parkes observations for project P1014 semester 2019APRS_04

description: The spatial distribution of neutral gas is important for understanding the interstellar medium (ISM) evolution and star formation. However, the distribution of Tiny Scale Atomic Structures (TSAS), especially the extremely small scale structures with spatial scales ranging from a few to hundreds of AU are largely unexplored. The formation and evolution of TSAS are still on an active debate. Multi-epoch observations of HI absorption against pulsars are a tested, practical observational method to probe the TSAS, due to pulsar’s nature on-off state and proper motions of 1 to 100 AU per year. The new Parkes UWL receiver has a powerful capability to simultaneously observe not only the HI line, but nearly all the CH lines, the four L-band OH lines, several dozen C and H recombination lines, and possibly even denser tracers such as ammonia and formaldehyde. Detecting any of those along with the HI absorption would represent a major leap in our understanding of TSAS. A particularly interesting possibility is that we might discover molecular absorption associated with TSAS, which would then imply that TSAS are not transient structures. We thus propose two epoch observations, which are separated by about five months, for four bright pulsars with the new Parkes UWL receiver using multiple spectral windows for probing structures ranging from 0.5 to 500 AU, monitoring the evolution of a known TSAS traced by PSR B1557-50, and try and detect other interstellar molecules in the TSAS.

title: Parkes observations for project P1008 semester 2019APRS_03

description: Magnetic field measurements of the Solar wind (SW) are extremely challenging, especially at close angular distances from the Sun. If they are obtained by measuring Faraday rotation of the radiation of background sources like active galactic nuclei, they are typically dependent on models of the electron density distribution in the heliosphere. However, pulsars can provide simultaneous, model-independent measurements of the electron density along the line-of-sight, along with Faraday Rotation estimates, and thus direct measurements of the SW magnetic field. Moreover, high-precision pulsar timing experiments such as Pulsar Timing Arrays (PTAs) can be strongly affected by the free electron distribution in the SW, and it is fundamentally important to understand, model and mitigate its influence on PTAs signals. With this proposal we aim to obtain high-cadence and precise measurements of the magnetic field and the electron density distribution of the SW by tracking three pulsars with low- to mid-ecliptic latitudes during their Solar approaches, and to reconstruct the SW dependence on the heliographic latitude. This will allow us to characterise the magnetic field of the SW and to collect precious information about the short-term fluctuations in the electron density that can appear as correlated noise in PTAs.

title: Optical polarimetric observations of the black hole binary star Cyg X-1 with RoboPol

description: The dataset contains raw FITS images of the black hole X-ray binary star Cyg X-1, raw FITS images of a nearby field star used for the interstellar polarization correction and processed measurements of polarimetric standards used for the instrumental polarization correction. The dataset was obtained with the RoboPol optical polarimeter in the R-band mounted at the 1.3 m telescope of the Skinakas Observatory, Greece. The data were collected between 13 May and 1 June 2022.<br>

title: Developmental timing of programmed DNA elimination in Paramecium tetraurelia recapitulates germline transposon evolutionary dynamics

description: With its nuclear dualism, the ciliate <em>Paramecium</em> constitutes an original model to study how host genomes cope with transposable elements (TEs). <em>P. tetraurelia</em> harbors two germline micronuclei (MIC) and a polyploid somatic macronucleus (MAC) that develops from the MIC at each sexual cycle. Throughout evolution, the MIC genome has been continuously colonized by TEs and related sequences that are removed from the somatic genome during MAC development. Whereas TE elimination is generally imprecise, excision of ~45000 TE-derived Internal Eliminated Sequences (IESs) is precise, allowing for functional gene assembly. Programmed DNA elimination is concomitant with genome amplification. It is guided by non-coding RNAs and repressive chromatin marks. A subset of IESs are excised independently of this epigenetic control, raising the question of how they are targeted for elimination. To gain insight into the determinants of IES excision, we determined the developmental timing of DNA elimination genome-wide by combining fluorescence-assisted nuclear sorting with next-generation sequencing. Essentially all IESs are excised within one endoduplication round only (32C to 64C), while TEs are eliminated at a later stage. We show that time, rather than replication, controls the progression of DNA elimination. Further analyses defined four IES classes according to excision timing and revealed that the earliest excised IESs tend to be independent of epigenetic factors, display strong sequence signals at their ends and originate from the most ancient integration events. We conclude that old IESs have been optimized during evolution for early and accurate excision, by acquiring stronger sequence determinants and escaping epigenetic control.
