Unveiling the Enigma of SN Zwicky: A Supernova Shaped by Cosmic Lensing
In the ever-expanding realm of astronomical discoveries, a peculiar image recently captured the attention of astronomers and stargazers alike. Dubbed "SN Zwicky," this supernova's radiance was so profoundly influenced by the gravitational pull of another galaxy that it manifested as multiple images in the night sky, an occurrence known as gravitational lensing. In this blog post, we delve into the fascinating tale of SN Zwicky, shedding light on its discovery, the intriguing phenomenon of gravitational lensing, and the promising insights it offers into the cosmos.
The Stellar Showstopper: SN Zwicky
SN Zwicky, also recognized as SN 2022qmx, made its celestial debut through the vigilant eyes of the Zwicky Transient Facility (ZTF). Nestled at the Palomar Observatory near San Diego, the ZTF orchestrated the grand reveal of this cosmic spectacle. This discovery is a pivotal contribution to the most extensive supernova survey to date, setting the stage for unparalleled cosmic revelations.
The Marvel of Gravitational Lensing
Gravitational lensing, the cosmic spectacle at the heart of SN Zwicky's allure, is a phenomenon of profound beauty and complexity. This cosmic trickery transpires when the gravity of a massive object, such as a galaxy, warps the path of light from a distant celestial body. Like a lens, it bends and concentrates the light, often resulting in multiple images of the same object.

Einstein's Prediction Realized
Gravitational lensing, a concept proposed by Albert Einstein over a century ago, has since become a fundamental element of astrophysical exploration. Einstein's groundbreaking theory foretold that the gravitational force of massive objects could bend the trajectory of light. The extent of this warping depends on the object's density and the distance between it and the observer.
A Rare Cosmic Encounter
Gravitational lensing of light has been a subject of fascination since its confirmation in 1919, shortly after Einstein's theory's inception. However, the ephemeral nature of supernovae makes events like SN Zwicky exceptionally challenging to detect. Although lensed images of distant objects like quasars have been documented, only a few supernovae with duplicated images have been observed. SN Zwicky and its predecessor, ciPTF16geu, both observed at Palomar, are among this exclusive group.
SN Zwicky's Unique Lensing
What sets SN Zwicky apart is its status as the smallest resolved gravitational lens system identified with optical telescopes. While its predecessor, ciPTF16geu, boasted a broader lens system, SN Zwicky's lensing effect exhibited greater magnification.
A Multifaceted Study
To comprehend the intricacies of SN Zwicky's gravitational lensing, an international team of astronomers harnessed an array of astronomical tools. The W. M. Keck Observatory's Near-IR Camera 2 (NIRC2) on Maunakea in Hawai‘i played a pivotal role in revealing the multiple images created by the supernova's lensing.
Unveiling the Cosmic Puzzle
SN Zwicky, classified as a Type Ia supernova, offers more than just a celestial spectacle. These supernovae, characterized by consistent brightness across events, played a crucial role in uncovering the universe's accelerated expansion, driven by the enigmatic force known as dark energy.
