Early life and education

Indumathi D. grew up in Chennai. [2]  Her father was a mechanical engineer, whose work inspired curiosity in her at a young age. [2]   Indumathi did her masters in Physics from the Madras Christian College, Chennai. [4] Even though she was more passionate about playing Cricket, an injury led her to pursue a career in Physics. [2] [3]

Indumathi D. obtained her PhD from IMSc in particle physics, [4] where she worked on the spin structure of the photon. [4] Her doctoral advisor was M.V.N. Murthy. As a student, she also wrote a paper on the supernova event SN1987A. [4] [5]  Following her postdoctoral appointments at Physical Research Laboratory(PRL), Ahmedabad, the University of Dortmund in Germany, and then a brief stay at the Indian Institute of Science, Bengaluru, she was appointed a faculty member at Harish Chandra Research Institute, Allahabad. [4]   She returned to IMSc in 1998. [4]

Research

Indumathi’s primary area of research is high energy physics phenomenology. Her research interests include work on atmospheric and solar neutrinos, nucleon and nuclear structure functions, inclusive hadroproduction at colliders and QED at finite temperature. [1] [4] She has authored several research papers on these topics. [6] [7]

Along with other Indian scientists, Indumathi D. has been a proponent of Indian Neutrino Observatory (INO)  which is a project to build the first underground observatory to study atmospheric neutrinos in India. [2] [3] [8] She has been the outreach coordinator [9] [10] and one of the spokespersons [11] [12] for the INO collaboration. She also coordinated a subgroup working on designing INO’s proposed main detector. [13] Indumathi D. has written articles about the feasibility, status and physical possibilities of the INO detectors. [14] [15]

Personal life

Indumathi D. is married to a computer scientist and they have two daughters, both of whom are adopted. [2] She has pointed to additional domestic chores as being a reason for the attrition rate of women in science, a dynamic she said is absent in her family. [2]

<span class="mw-page-title-main">Neutrino</span> Elementary particle with extremely low mass

A neutrino is a fermion that interacts only via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero. The rest mass of the neutrino is much smaller than that of the other known elementary particles excluding massless particles. The weak force has a very short range, the gravitational interaction is extremely weak due to the very small mass of the neutrino, and neutrinos do not participate in the strong interaction. Thus, neutrinos typically pass through normal matter unimpeded and undetected.

<span class="mw-page-title-main">Cowan–Reines neutrino experiment</span> Institute of Technology Experimental confirmation of neutrinos

The Cowan–Reines neutrino experiment was conducted by physicists Clyde Cowan and Frederick Reines in 1956. The experiment confirmed the existence of neutrinos. Neutrinos, subatomic particles with no electric charge and very small mass, had been conjectured to be an essential particle in beta decay processes in the 1930s. With neither mass nor charge, such particles appeared to be impossible to detect. The experiment exploited a huge flux of electron antineutrinos emanating from a nearby nuclear reactor and a detector consisting of large tanks of water. Neutrino interactions with the protons of the water were observed, verifying the existence and basic properties of this particle for the first time.

<span class="mw-page-title-main">Solar neutrino</span> Extremely light particle produced by the Sun

A solar neutrino is a neutrino originating from nuclear fusion in the Sun's core, and is the most common type of neutrino passing through any source observed on Earth at any particular moment. Neutrinos are elementary particles with extremely small rest mass and a neutral electric charge. They only interact with matter via the weak interaction and gravity, making their detection very difficult. This has led to the now-resolved solar neutrino problem. Much is now known about solar neutrinos, but the research in this field is ongoing.

<span class="mw-page-title-main">Neutrino detector</span> Physics apparatus which is designed to study neutrinos

A neutrino detector is a physics apparatus which is designed to study neutrinos. Because neutrinos only weakly interact with other particles of matter, neutrino detectors must be very large to detect a significant number of neutrinos. Neutrino detectors are often built underground, to isolate the detector from cosmic rays and other background radiation. The field of neutrino astronomy is still very much in its infancy – the only confirmed extraterrestrial sources as of 2018 are the Sun and the supernova 1987A in the nearby Large Magellanic Cloud. Another likely source is the blazar TXS 0506+056 about 3.7 billion light years away. Neutrino observatories will "give astronomers fresh eyes with which to study the universe".

Herbert Hwa-sen Chen was a theoretical and experimental physicist at the University of California at Irvine known for his contributions in the field of neutrino detection. Chen's work on observations of elastic neutrino-electron scattering provided important experimental support for the electroweak theory of the standard model of particle physics. In 1984 Chen realized that the deuterium of heavy water could be used as a detector that would distinguish the flavors of solar neutrinos. This idea led Chen to develop plans for the Sudbury Neutrino Observatory that would eventually make fundamental measurements demonstrating that neutrinos were particles with mass.

Supernova neutrinos are weakly interactive elementary particles produced during a core-collapse supernova explosion. A massive star collapses at the end of its life, emitting on the order of 1058 neutrinos and antineutrinos in all lepton flavors. The luminosity of different neutrino and antineutrino species are roughly the same. They carry away about 99% of the gravitational energy of the dying star as a burst lasting tens of seconds. The typical supernova neutrino energies are 10 to 20 MeV. Supernovae are considered the strongest and most frequent source of cosmic neutrinos in the MeV energy range.
