  • Formation of the Active Star Forming Region LHA 120-N 44 Triggered By

We carried out a detailed analysis of Hi at 60 arcsec resolution by using the ATCA & Parkes data. We presented decomposition of the Hi emission into two velocity components (the L- and D-components) with the velocity separation of ∼60 km s−1. In addition, we newly defined the I-component whose velocity is intermediate between the L- and D-components. The D-component was used to derive the rotation curve of the LMC disk, which is consistent with the stellar rotation curve (Alves & Nelson 2000). Toward the active cluster forming region of LHA 120-N 44, the three velocity components of Hi gas show signatures of dynamical interaction including bridges and complementary spatial distributions.

  • Photons That Travel in Free Space Slower Than the Speed of Light Authors
    Title: Photons that travel in free space slower than the speed of light Authors: Daniel Giovannini1†, Jacquiline Romero1†, Václav Potoček1, Gergely Ferenczi1, Fiona Speirits1, Stephen M. Barnett1, Daniele Faccio2, Miles J.

However, light beams have finite transverse size, which leads to a modification of their wavevectors resulting in a change to their phase and group velocities. We study the group velocity of single photons by measuring a change in their arrival time that results from changing the beam’s transverse spatial structure. Using time-correlated photon pairs we show a reduction of the group velocity of photons in both a Bessel beam and photons in a focused Gaussian beam. In both cases, the delay is several microns over a propagation distance of the order of 1 m. Our work highlights that, even in free space, the invariance of the speed of light only applies to plane waves. Introducing spatial structure to an optical beam, even for a single photon, reduces the group velocity of the light by a readily measurable amount. One sentence summary: The group velocity of light in free space is reduced by controlling the transverse spatial structure of the light beam. Main text The speed of light is trivially given as �/�, where � is the speed of light in free space and � is the refractive index of the medium.

Padgett2, y 1Department of Opto-electronic Engineering, Beihang University, Beijing, 100191, China 2SUPA, School of Physics and Astronomy, University of Glasgow, Glasgow, G12 8QQ, UK 3Selex ES, Edinburgh, UK Time-of-flight three dimensional imaging is an important tool for many applications, such as object recognition and remote sensing. Unlike conventional imaging approach using pixelated detector array, single-pixel imaging based on projected patterns, such as Hadamard patterns, utilises an alternative strategy to acquire information with sampling basis. Here we show a modified single-pixel camera using a pulsed illumi- nation source and a high-speed photodiode, capable of reconstructing 128×128 pixel resolution 3D scenes to an accuracy of ∼ 3 mm at a range of ∼ 5 m. Furthermore, we demonstrate continuous real-time 3D video with a frame-rate up to 12 Hz. The sim- plicity of the system hardware could enable low-cost 3D imaging devices for precision ranging at wavelengths beyond the visible spectrum. Introduction Whilst a variety of 3D imaging technologies are suited for different applications, time-of-flight (TOF) systems have set the benchmark for performance with regards to a combination of accuracy and operating range. Time-of-flight imaging is performed by illuminating a scene with a pulsed light source and observing the back-scattered light. Correlating the detection time of the back-scattered light with the time of the illumination pulse allows the distance, d, to objects within the scene to be estimated by d = tc=2, where t is the TOF and c is the propagation speed of light.

  • The Cataclysmic Variable AE Aquarii: Orbital Variability in V Band
    The cataclysmic variable AE Aquarii: orbital variability in V band R. Zamanov & G. Latev Institute of Astronomy and National Astronomical Observatory, Bulgarian Academy of Sciences, Tsarigradsko Shose 72, BG-1784 Sofia, Bulgaria [email protected] [email protected] (Submitted on 28.11.2016. Accepted on 31.01.2017) Abstract. We present 62.7 hours observations of the cataclysmic variable AE Aqr in Johnson V band. These are non-published archive electro-photometric data obtained during the time period 1993 to 1999. We construct the orbital variability in V band and obtain a Fourier fit to the double-wave quiescent light curve. The strongest flares in our data set are in phase interval 0.6 - 0.8. The data can be downloaded from http://www.astro.bas.bg/∼rz/DATA/AEAqr.elphot.dat. Key words: Stars: novae, cataclysmic variables – Accretion, accretion disks – white dwarfs – Stars: individual: AE Aqr 1 Introduction AE Aqr is a bright intermediate polar cataclysmic variable (V ≈ 11−12.3). In this semi-detached binary system a spotted K type dwarf (K0-K4 IV/V star) transfers material through the inner Lagrangian point L1 toward a magnetic white dwarf (Skidmore et al. 2003, Hill et al. 2016). It has a relatively long orbital period of 9.88 hours (Robinson et al. 1991; Echevarr´ıa et al. 2008) and an extremely short rotational period of the white dwarf of only 33 s (Patterson et al. 1980). To appear in such a state, AE Aqr should be a former supersoft X-ray binary, in which the mass transfer rate in the recent past (≈ 107 yr) has been much higher than its current value (Schenker et al.

  • Search for Gamma-Ray Emission from AE Aquarii with Seven Years of FERMI-LAT Observations
    Search for gamma-ray emission from AE Aquarii with seven years of FERMI-LAT observations Jian Li1, Diego F. Torres1,2, Nanda Rea1,3, Emma de O˜na Wilhelmi1, Alessandro Papitto4, Xian Hou5, & Christopher W. Mauche6 ABSTRACT AE Aquarii (AE Aqr) is a cataclysmic binary hosting one of the fastest rotating (Pspin = 33.08 s) white dwarfs known. Based on seven years of Fermi Large Area Tele- scope (LAT) Pass 8 data, we report on a deep search for gamma-ray emission from æ. Using X-ray observations from ASCA, XMM-Newton, Chandra, Swift, Suzaku, and NuSTAR, spanning 20 years, we substantially extend and improve the spin ephemeris of æ. Using this ephemeris, we searched for gamma-ray pulsations at the spin period of the white dwarf. No gamma-ray pulsations were detected above 3 σ significance. Neither phase-averaged gamma-ray emission nor gamma-ray variability of æ is de- tected by Fermi-LAT. We impose the most restrictive upper limit to the gamma-ray flux from æ to date: 1.3 × 10−12 erg cm−2 s−1 in the 100 MeV–300 GeV energy range, providing constraints on models. Subject headings: gamma rays: stars — cataclysmic binary: individual: æ 1. Introduction Cataclysmic variables (CVs) are semi-detached binaries consisting of a white dwarf (WD) and a companion star, usually a red dwarf. æ is a bright (V≈11, Welsh et al. 1999) CV hosting one of the fastest rotating WDs known (Pspin = 33.08 s, Patterson 1979) and a K 4-5 V secondary; it is arXiv:1608.06662v1 [astro-ph.HE] 23 Aug 2016 1Institute of Space Sciences (IEEC-CSIC), Campus UAB, Carrer de Magrans s/n, 08193 Barcelona, Spain 2Instituci´oCatalana de Recerca i Estudis Avanc¸ats (ICREA), E-08010 Barcelona, Spain 3Anton Pannekoek Institute, University of Amsterdam, Postbus 94249, NL-1090-GE Amsterdam, The Netherlands 4INAF-Osservatorio Astronomico di Roma, via di Frascati 33, I-00040 Monte Porzio Catone, Roma, Italy 5Key Laboratory for the Structure and Evolution of Celestial Objects, Yunnan Observatories, Chinese Academy of Sciences, Kunming 650216, China.
