About

The primary focus of Priyanka's research is high-resolution X-ray spectroscopy. She uses data from high-resolution spectral data from telescopes such as Chandra, XMM-Newton, and Hitomi to addresses fundamental inquiries surrounding accretion disk winds, relativistic jets in X-ray binaries (XRBs), properties of the Intra-cluster medium, (ICM), and the growth of galaxy clusters. Priyanka is a member of the XRISM team, and serving as PI and Co-I, she has obtained over $600,000 in NASA observational grants, including fundings from Chandra, XRISM, and NuSTAR. She is an expert in modeling both collisionally-ionized and photoionized plasma, and has been an active developer of the spectral synthesis codes - AtomDB and Cloudy for several years. Priyanka's expertise extends to multiwavelength studies, spanning microwave, optical, and near-infrared bands, utilizing Planck SZ observations for galaxy groups and SDSS data to probe quasar distribution within dark matter halos.

Telescopes and Instruments

Chandra

The Chandra X-ray Observatory is NASA’s flagship X-ray observatory, providing essential data on everything from the environment surrounding newborn stars to the emissions from hot plasma inside galaxy clusters. The Smithsonian Astrophysical Observatory (SAO), as part of the Center for Astrophysics | Harvard & Smithsonian, manages Chandra’s day-to-day operations, providing spacecraft control, observation planning, and data processing for astronomers. Chandra is one of NASA’s orbiting Great Observatories, along with the Hubble.

Einstein Observatory

NASA’s Einstein Observatory was the first X-ray space telescope designed to produce images of astronomical X-ray sources. The spacecraft operated from 1978 through 1981, providing important observations of pulsars, supernova remnants, supermassive black holes in other galaxies, and many more, paving the way for NASA’s Chandra X-ray Observatory. The X-ray telescope was designed by researchers at the Center for Astrophysics | Harvard & Smithsonian.

Lynx X-Ray Observatory

The Lynx X-ray Observatory is a proposed X-ray space telescope, designed to be the next generation following NASA’s Chandra X-ray Observatory and the European Space Agency’s upcoming Athena Telescope. This observatory will be able to take images of a larger area of the sky in X-ray light with better resolution than any existing telescope, allowing astronomers to study the first supermassive black holes, the hot gas surrounding galaxies as they evolve, and radiation from the earliest stars. Researchers from the Center for Astrophysics | Harvard & Smithsonian and other universities are presenting Lynx to NASA for consideration in the 2020 Decadal Survey, with a proposed launch date in the mid-2030s.

South Pole Telescope, Antarctica

The South Pole Telescope (SPT) is a submillimeter observatory in Antarctica that performs measurements of the cosmic microwave background (CMB) and the dark energy driving the acceleration of the expansion of the universe. The observatory is also part of the Event Horizon Telescope (EHT), a globe-spanning multi-telescope project that captured the first image of a black hole at the center of a nearby galaxy. The SPT project is a collaboration between the University of Chicago, the University of California at Berkeley, Case Western Reserve University, the University of Illinois, and the Center for Astrophysics | Harvard & Smithsonian.
