    The galaxy SDSSJ0952+2143 showed remarkable emission-line properties first reported in 2008 (paper I), which are the consequence of a powerful high-energy flare. Here we report follow-up observations of SDSSJ0952+2143, and discuss outburst scenarios in terms of stellar ...

    We report our work on liquid rotor electret power generators (LEPG). LEPG devices are essentially fixed-charged, Teflon-electret capacitors with air-filled gaps and liquid droplets that move by vibration. As the liquid moves into and out of the gaps, a net voltage is ge...

    In this paper we report on a holographic method used to record fast events in the nanosecond time scale. Several frames of the expansion of shock waves in air and in a polymer sample are recorded holographically in a single shot experiment, using a pulse train generated...

    Line intensity mapping (LIM) is a promising approach to study star formation and the interstellar medium (ISM) in galaxies by measuring the aggregate line emission from the entire galaxy population. In this work, we develop a simple yet physically-motivated framework fo...

    The \hi 21 cm transition line is expected to be an important probe into the cosmic dark ages and epoch of reionization. Foreground source removal is one of the principal challenges for the detection of this signal. This paper investigates the extragalactic point source ...

    A new K-band (2.0-2.4 µm) image of the gravitational lens system 2016 + 112 gives the clearest view yet obtained of the two lensing galaxies, which have K magnitudes of 17.2 and ~ 18. The fainter galaxy is extremely red, with r-K of ≈7.7 mag, and while no spectroscopic ...

    None: The nucleotide sequence of the repressor gene C of the temperate phage P2 has been determined. It codes for a nonbasic polypeptide, 99 amino acids long. Twelve repressor-defective mutants have been mapped. All but one are located within the presumed coding part of...

    Ultraviolet detection is often required to be made in the presence of a strong background of solar radiation which needs to be suppressed, but materials limitations at these wavelengths can impact both filter and sensor performance. In this work, we explore the use of 1...
