Astronomers using NASA's Hubble Space Telescope have imaged what may be water vapor plumes erupting off the surface of Jupiter's moon Europa. This finding bolsters other Hubble observations suggesting the icy moon erupts with high altitude water vapor plumes. The observation increases the possibility that missions to Europa may be able to sample Europa's ocean without having to drill through miles of ice. "Europa's ocean is considered to be one of the most promising places that could poten...

Airbus Defence and Space is continuing to future-proof its site at Friedrichshafen, Germany, with the construction of a new Integrated Technology Centre (ITC). At the heart of the four-storey centre with a basement and a footprint of around 4,200 m² will be a large central clean room for the development and construction of satellites. The building, with dimensions of around 70 x 60 metres and a height of over 20 metres, will be an expansion of the existing Hall 6 – the current sa...

Brief but powerful outbursts seen from Comet 67P/Churyumov-Gerasimenko during its most active period last year have been traced back to their origins on the surface. In the three months centred around the comet's closest approach to the Sun, on 13 August 2015, Rosetta's cameras captured 34 outbursts. These violent events were over and above regular jets and flows of material seen streaming from the comet's nucleus. The latter switch on and off with clockwork repeatability from one comet ro...

Two's company, but three might not always be a crowd - at least in space. Astronomers using NASA's Hubble Space Telescope, and a trick of nature, have confirmed the existence of a planet orbiting two stars in the system OGLE-2007-BLG-349, located 8,000 light-years away towards the center of our galaxy. The planet orbits roughly 300 million miles from the stellar duo, about the distance from the asteroid belt to our sun. It completes an orbit around both stars roughly every seven years. The...

International teams of astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to explore the distant corner of the Universe first revealed in the iconic images of the Hubble Ultra Deep Field (HUDF). These new ALMA observations are significantly deeper and sharper than previous surveys at millimetre wavelengths. They clearly show how the rate of star formation in young galaxies is closely related to their total mass in stars. They also trace the previously unknown abundance...

An international team using ALMA, along with ESO's Very Large Telescope and other telescopes, has discovered the true nature of a rare object in the distant Universe called a Lyman-alpha Blob. Up to now astronomers did not understand what made these huge clouds of gas shine so brightly, but ALMA has now seen two galaxies at the heart of one of these objects and they are undergoing a frenzy of star formation that is lighting up their surroundings. These large galaxies are in turn at the centre of...

The mystery of a rare change in the behaviour of a supermassive black hole at the centre of a distant galaxy has been solved by an international team of astronomers using ESO's Very Large Telescope along with the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory. It seems that the black hole has fallen on hard times and is no longer being fed enough fuel to make its surroundings shine. Many galaxies are found to have an extremely bright core powered by a supermassive black ...

By converging in orbit, a pair of small satellites will open a new view on the source of the largest structure in the Solar System: the Sun’s ghostly atmosphere, extending millions of kilometres out into space. The two satellites together are called Proba-3, set for launch in late 2019. Through precise formation flying, one will cast a shadow across the second to open up an unimpeded view of the inner area of the ‘corona’, which is a million times fainter than the blinding...

    Employment

     

    June 2007- : Research Associate at Leiden Observatory, Netherlands.Currently, I am working on project ASSIST (Adaptive Secondary Setup and Instrument STimulator) at Leiden Observatory. This system is being designed to allow for the testing of Adaptive Optics facility of Very Large Telescope. I am responsible for the development of MAIV (manufacturing, alignment, integration and verification) plan for this project. As the name suggests, the following items have been covered as a part of this procedure:

    • Procurement of various items for ASSIST.
    • Plan to assemble and integrate ASSIST bench for testing in Leiden; which handling and testing tools are required.
    • Development of a strategy for the alignment of various optics and opto-mechanics of ASSIST.
    • Identifying tools and equipments required during alignment and integration, such as alignment telescope and measurement arm.
    • Identify the tests which are to be performed on the subsystems, and on the assembly.
    • Assembly of ASSIST at ESO, which also includes assembly of DSM (Deformable Secondary Mirror) on top of ASSIST.

     

    In this role, I take part in preparing Call for tender documents for the optical modules and preparing reports for Preliminary Design Review and Final Design Review.

     

    In the same project, I am in-charge for the Star Simulator module which will simulate NGS (Natural Guide Stars) and LGS (Laser Guide Stars) for ASSIST. The main tasks for this module are:

     

    • Converting technical specifications of ASSIST into size, brightness and wavelength of required sources for ASSSIST.
    • Talk with different vendors to find out correct LED, fibers etc for NGS sources.
    • Experiments conducted in Leiden Optical Lab to check whether theoretical calculations match with experimental results.
    • Interaction with Mechanical Workshop to build a prototype for NGS and LGS.

     

    I also take part in testing phase screens which simulate turbulence of the atmosphere. These phase screens are being tested at European Southern Observatory in Garching using a Shack Hartmann wavefront sensor.

     

    I am also involved in project MICADO (MCAO Imaging CAmera for Deep Observations). MICADO is the imaging camera for the multi-conjugate adaptive optics system on the 42-m European Extremely Large Telescope. We create simulations assuming most of the parameters such as background, pixel scale, read-noise, throughput etc what might be expected from the E-ELT instrument MICADO. Then we compute the accuracy with which photometry can be done on these images using current software packages.

     

    • 2006 – June 2007: Research scholar, IUCAA, Pune, India. A high speed Data Acquisition Board (DAB) for optical and infrared detectors using USB 2.0 was designed using Orcad software. DAB has five fiber-optic links with each link connected to a separate detector/Controller. Simultaneous data transfer is possible through all fiber links. It has 1GB flash-memory and the fibre link data can be acquired either to the flash memory or to the USB port. A minimum data rate per fiber link of 1Mbps is sustainable (if USB is shared by multiple fiber links).  In the unshared or read-to-flash mode, maximum data rate per fiber link of at least 10 Mbps is possible.
    • 2000 - 2006: Research Fellow of CSIR, IUCAA, Pune, India. During this period I worked on my PhD thesis. My work mainly involved the design and fabrication of a near-infrared imager to be used with IUCAA telescope. I worked on all the aspects of astronomical instrumentation – optical design, mechanical design, data acquisition, detector testing, vacuum and cryogenics, data reduction, programming in C etc.
    • 1998 - 2000: Lecturer in Bareilly College, Bareilly.
    • 1997 - 1998: Research assistant at Indian Institute of Technology, Kanpur.
