Dr. Nikhil Kute’s Post

On Wednesday at SPIE Astronomical Telescopes + Instrumentation, Dynavac's Director of Technology, Dr. Ramya Chandrasekaran, will present "Optical Coatings on Large Telescope Mirrors." Advanced telescope mirror coatings have become essential for enabling new and exciting astronomical discoveries. With their ability to maximize reflectivity, reduce scattering, withstand aggressive environments, and optimize specific optical properties, advanced thin film deposition systems help telescopes to see farther and fainter than ever before. Discover practical solutions to achieve uniform, high-performance coatings on large mirrors and explore the suitability of technologies like filament evaporation, electron beam evaporation, and magnetron sputtering. Gain insights into hardware design challenges and prevalent issues with mirror handling and long-run reliability. Learn more: https://lnkd.in/gN6qPHr9 #SPIEastro #Aerospace #telescope

After *many* years of work (started in 2016!) - our paper on transducer characterization for the Mars Sonic Anemometer has finally published in #JASA the Journal of the Acoustical Society of America. Great working with co-authors Rishabh Chaudhary, Don Banfield, Ian Neeson, Luisa Chiesa and Zijia Zhao. The paper shows that pressure and temperature effects on ultrasonic transducer performance should generate at most +/-2.3% error in wind speed measurement and +/-1.2% error in sound speed measurement for a practical instrument across the tested ranges of 2-10 mbar and -83C to +20C. This is yet more evidence that a sonic based wind sensor is the right choice for the next wind sensor to fly to the Red Planet. We are also flying similar instruments on stratospheric balloons here on Earth and hope to record unique data sets of relative wind at high resolution and high update rate. Many thanks to NASA - National Aeronautics and Space Administration for funding and supporting this work. #acoustics #Mars #anemometry

Sure, you know about Hubble and #JWST, but what do you known about the Event Horizon Telescope? Remember the famous black hole photo a few years ago? That’s EHT. And they’re back with an even more impressive image. #EHT isn't a telescope in the traditional sense. Instead, it's a collection of telescopes scattered around the globe. It’s created by interferometry, which uses light in the microwave regime of the electromagnetic spectrum captured at different locations. The recorded images are combined and processed to build an image with a resolution similar to that of a telescope the size of the most distant locations. Since the 1980s, physicists have been confident that there is a supermassive black hole at the center of the Milky Way galaxy. Dubbed Sagittarius A, the Event Horizon Telescope captured the first image two years ago. Now the collaboration has revealed a new polarized image showcasing the black hole's swirling magnetic fields. 🌌 #BlackHole #Physics #EventHorizon #Hubble #JWST

🔭 Here’s a fresh and intriguing article from the Astronomical Journal, published by the #American #Astronomical #Society. It begins with the following sentence: “Understanding when and how circumstellar #disks disperse is crucial to constrain #planet formation and #migration.” I believe this discovery would not have been possible without the spectrometry capabilities of the James Webb Space Telescope. Moreover, I hope it’s a significant step on humanity’s path to discovering Discworld. 😉 #spacescience #innovation #haveaniceweekend

Light possesses wave-particle duality, acting as both waves and particles known as photons. It travels at a constant speed in a vacuum (approximately 299,792 km/s). Light consists of electromagnetic waves with varying wavelengths and frequencies. It undergoes phenomena like refraction, reflection, dispersion, interference, and diffraction. Polarization refers to the orientation of the electric field vector. The photoelectric effect demonstrates light's particle-like behavior. These properties are fundamental to optics, quantum mechanics, and have practical applications in various scientific fields and technologies. #galaxyaerosgh #space #spaceexploration #spacenews

Euclid's sight has been finally restored. On 1st July 2023, Euclid was launched and later deployed on the Sun-Earth Lagrange point 2, 1.5 million km from Earth. Its mission was to study the nature of dark energy and dark matter, but soon a few nanometres of ice accumulated on the mission's optics and critically diminished the light captured by the sensors. For months, the mission team worked devising a procedure to heat up individual mirrors in the instrument’s optical system from -147°C to -113°C, without interfering with the mission’s calibration or producing interference with other systems. Now it's been announced that the procedure has been a success and Euclid's sight has been restored. https://lnkd.in/dJWY_sP3 #physics #physicsnews #astrophysics #astronomy #euclid #darkmatter #darkenergy

5 years ago, the Event Horizon Telescope (EHT) captured the first image of a black hole 📷 - 55 million light-years away at the center of the M87 galaxy 🌌. Due to the incredibly strong gravitational pull, even light can’t escape from black holes. However, the researchers managed to outsmart physics to a certain extent and created an image of a black hole's shadow. And just recently, scientists from the EHT collaboration also succeeded in using polarized light to reveal magnetic fields surrounding black holes. Happy to see what EHT is capable of - knowing that ALMA (Atacama Large Millimeter/Submillimeter Array) telescopes, whose developers rely on PI’s hexapod positioning systems, are an integral part of the EHT system. 📌 https://lnkd.in/e_xH5nwa #blackhole #ALMA #EHT #telescope #hexapods
