| Global VLBI imaging of the gravitational lens MG J0751+2716 | John McKean |Gravitational lensing is the deflection of light from a distant background object (the source) by an intervening mass distribution (the lens). If the surface mass density of the lens is sufficiently high, then multiple images of the background source, which are often highly magnified and distorted, are produced. The gravitational lensing phenomena is beautifully illustrated in this global very long baseline interferometry image of MG J0751+2716 at redshift 3.2. Here, the extended background radio source is highly distorted into several images, some of which are stretched to form large gravitational arcs. Never before has such high angular resolution of extended arcs been seen before, which highlights the excellent sensitivity that can be achieved with VLBI arrays today (a collecting area that is about 10 per cent of the SKA). | {{:propaganda:appp2014:mckean_poster1_new.pdf|}} {{ :propaganda:appp2014:mckean_poster1_new.png?150 }} RAW: {{:propaganda:appp2014:mckean_poster1.key.tar}} |  |
| PSR B0823+26: Emission modes in single pulses | Charlotte Sobey |PSR B0823+26 displays a plethora of magnetospheric emission characteristics over a wide range of timescales.  Single-pulse data from the LOFAR (Low Frequency Array) telescope aided in the detection of a sporadic and weakly-emitting 'quiet’ mode over hour-long periods, which displays rotating radio transient-like features with a nulling fraction forty-times greater than that during the more regularly-emitting 'bright’ mode. Furthermore, the transition from the newly-discovered 'quiet’ mode to the 'bright’ mode occurs within one rotational period of the pulsar (0.5 s) and is concurrent across a broad range of radio frequencies.  Studying such pulsars furthers insight into the relationship between the host of magnetospheric radio emission characteristics and understanding of the physical mechanism behind this.  (c) C.

| PSR J1023+0038 transforming between a radio pulsar and an accreting system | Anne Archibald | [NOTE: the paper appears in print July 20th, possibly accompanied by a press release and video, so this might be a good time to post the image.] PSR J1023+0038 is a neutron star spinning 592 times per second, orbited by a small Sun-like star. We think all such fast-spinning neutron stars were spun up by accreting material spiraling in from a companion. We have actually seen this system switch back and forth between a radio pulsar (left) and an X-ray bright system with a disc of accreting material (right). Right now, in fact, the system is in this mysterious accreting state. When the accretion switches off, will the neutron star have spun up, slowed down, or stayed the same?

| PSR J0337+1715: a millisecond pulsar in a stellar triple system | Anne Archibald | Radio telescopes, including the Westerbork Synthesis Radio Telescope operated by ASTRON, allow us to measure how early or late the pulses from this radio pulsar are as it moves around its orbit. We can then compute the delays - shown above - due to the interaction of the inner and outer orbit. These measurements, and the tremendous density of the pulsar, let us test one of the foundations of Einstein's theory of gravity, the Strong Equivalence Principle.

| Global VLBI imaging of the gravitational lens JVAS B1938+666 | John McKean | [Not ready for AJDI release] Gravitational lensing is the deflection of light from a distant background object (the source) by an intervening mass distribution (the lens). If the surface mass density of the lens is sufficiently high, then multiple images of the background source, which are often highly magnified and distorted, are produced. The gravitational lensing phenomena is beautifully illustrated in this global very long baseline interferometry image of JVAS B1938+666 at redshift 2.0. Here, the extended background radio source is highly distorted into several images, some of which are stretched to form large gravitational arcs.

|Apertif | Tom Oosterloo| The sky as Apertif will see it. The blue objects show the radio continuum emission from star forming galaxies and from galaxies with an Active Galactic Nucleus. The orange objects illustrate the cold, atomic Hydrogen in galaxies. Apertif will detect the Hydrogen in more than 100,000 galaxies, and the continuum emission from about 10,000,000 objects | {{:propaganda:appp2014:apertif.pdf|}} {{:propaganda:appp2014:apertif.png?150| }}|  |
|Dwingeloo 1 & 2 | Tom Oosterloo| Dwingeloo 1 and 2 were discovered with the Dwingeloo dish in 1994 as part of a search for galaxies that are hidden by dust clouds in the plane of the Milky Way. Such dust clouds block the optical light of galaxies, but are transparent for their radio emission. Therefore, surveying the plane of the Milky Way with radio telescopes can reveal galaxies that are otherwise hard to see. In optical light, Dwingeloo 1 and 2 are almost invisible, but they have bright radio emission. The picture shows the radio image of Dwingeloo 1 and 2 made with the Westerbork Synthesis Radio Telescope| {{:propaganda:appp2014:dwloo12poster-2.pdf|}}{{:propaganda:appp2014:dwloo12poster-2.png?150|}}|

|NGC 891 | Tom Oosterloo| The HI halo of NGC 891. Very deep observations with the Westerbork Synthesis Radio Telescope have revealed large amounts of cold, atomic gas in the halos of nearby spiral galaxies. Part of such gaseous halos is connected to star formation in the disk, while some of the gas, in particular the clouds far from the disk, are filaments being accreted from the surrounding intergalactic medium|{{:propaganda:appp2014:n8912011poster.pdf|}} {{:propaganda:appp2014:n8912011poster.png?150| }}|  |

|Leo P | Betsey Adams| HST data is unpublished and the work of a collaborator. An AJDI (with longer write-up) will be submitted when paper is published - do NOT place in queue until then. Caption: Leo P is an extreme star forming galaxy discovered via its neutral hydrogen content in the ALFALFA HI survey. Leo P is among the most metal poor galaxies known and relatively nearby, allowing in depth studies of the star formation process in pristine material. Deep observations with the Hubble Space Telescope resolve the population into individual stars. These observations will allow us to constrain both the star formation and the chemical evolution history of Leo P. Image credit: K.

Caption: Neutral hydrogen contours of AGC198606 from observations with Westerbork are overplotted on deep optical data taken with ODI on the WIYN 3.5m telescope. Identified  as a gas cloud in the ALFALFA HI Survey, AGC198606 is an excellent candidate to represent a gas-bearing dark matter halo with (almost) no stellar population in our own Local Group. The deep optical image reveals no associated stellar component but does result in the detection of new background galaxy clusters. Image Credit: E. A.K. Adams (ASTRON) and S.

|Low-Frequency Profiles of Millisecond Pulsars at 150 MHz with LOFAR | Vlad Kondratiev | [NOTE: Paper is nearly submitted. AJDI will be submitted when paper is accepted.] Low-frequency profiles of millisecond pulsars (MSPs) with LOFAR at the frequency range of 110-188 MHz. LOFAR detected 46 MSPs out of 57 observed so far. This is the largest sample of MSPs ever observed and detected with a single radio telescope at these low frequencies. Regular monitoring of pulsar dispersion and rotation measures and scattering in the interstellar medium (ISM) will provide an "ISM weather report" to improve pulsar timing precision at higher observing frequencies. | {{:propaganda:appp2014:lofar-msp-profiles-invert2.pdf|}}{{:propaganda:appp2014:lofar-msp-profiles-invert2.jpg?150|}}|  |

|The Crab Pulsar and the Crab Nebula | Joeri van Leeuwen| The Crab Pulsar and the Crab Nebula are one impressive pair as seen with Westerbork and the VLT. Only 10 miles across but 500.000 times as massive as the Earth, the pulsar is a cosmic lighthouse that spins 30 times each second, sweeping around bundles of bright radio waves. In this image we see a 1-second snapshot of these peaked waves as they reach Westerbork/PuMaII after 6000 years of interstellar travel. | {{:propaganda:appp2014:JvL-Crab-02.pdf|}} {{ :propaganda:appp2014:JvL-Crab-01-Thumbnail.jpg?150 }}   RAW (Illustrator PDF):  {{:propaganda:appp2014:JvL-Crab-02.pdf}} |  |
