    Localizing Gravitational Wave Sources with Single-Baseline Atom Interferometers

    Localizing sources on the sky is crucial for realizing the full potential of gravitational waves for astronomy, astrophysics, and cosmology. We show that the mid-frequency band, roughly 0.03 to 10 Hz, has significant potential for angular localization. The angular location is measured through the changing Doppler shift as the detector orbits the Sun. This band maximizes the effect since these are the highest frequencies in which sources live several months. Atom interferometer detectors can observe in the mid-frequency band, and even with just a single baseline can exploit this effect for sensitive angular localization. The single baseline orbits around the Earth and the Sun, causing it to reorient and change position significantly during the lifetime of the source, and making it similar to having multiple baselines/detectors. For example, atomic detectors could predict the location of upcoming black hole or neutron star merger events with sufficient accuracy to allow optical and other electromagnetic telescopes to observe these events simultaneously. Thus, mid-band atomic detectors are complementary to other gravitational wave detectors and will help complete the observation of a broad range of the gravitational spectrum.Comment: 16 pages, 3 figures, 2 table

    The diploma thesis deal with the topic of sexual life of people suffering from the Parkinson's disease (PD). The theoretical part contains basic information about PD and the results of researches on sexuality of people with this illness, focusing on the agents that infl uence PD. The empirical part comprises of a research project implemented on a set of 103 people with PD. In order to describe the specifi cs of the patients' sexual lives, two sets of questions were designed (separate for men and women), containing a questionnaire on sociodemographic features, psychological (BDI-II, STAI) and sexuological questionnaires. The acquired data was statistically elaborated by means of the programme SPSS. Results of the sexuological questionnaires (GRISS, FSFI, SFŽ3, SFM, IIEF) show a decrease in sexual functions and a presence of sexual dysfunctions connected with PD. With the help of regressive models, it was elicited that in case of men with this illness, the most infl uential agent on their sexual life is depression and subjectively scoring the illness, in case of women the agent of depression and anxiety
