It is located 847 million light-years from Earth[1] and is said to be the nearest quasar (QSO) due to its high optical nuclear luminosity of MV = -23.8 mag.

[3] At the redshift of 0.0611,[4] I Zwicky 1 shows spectral properties of high-redshift quasars that are blueshifted by 1,350 km-1 according to the study conducted by Buson & Ulrich in 1990.

Given location in galactic molecular clouds, the carbon monoxide must be larger on the scale of the 26 kpc J = 1-0 beam size, with optical depth and being thermalized.

The star-forming rate, efficiency of the disk and the nucleus of I Zwicky 1 was estimated by researchers, whom they found that the values are similar to the luminosity of galaxies studied by IRAS.

Overall, the disc star formation, is closer to topmost values of ~30 L_sun_/M_sun_ that is found inside galactic star-forming regions of the Milky Way such as M17 or W51.

When looking at its nuclear near-infrared colors analysis, researchers suggest I Zwicky 1 has a combined quasar nucleus and defunct stellar component that matches about 10 to 20% of the flux density at 2.2 microns.

With 24 baselines provided by the four 15 m antennas, ranging from 24 to 288 m in length, they were supplied by SIS receivers with single-sideband (SSB) system temperatures of 170 K above the atmosphere.

To investigate the structure dynamics of the nucleus, which they reckoned these velocity maps together with p-v diagrams alongside major and minor kinematic axes of I Zwicky 1.

The observations in the H-band (1.65 m) on the other hand, were carried out in December 1995, at the William Herschel Telescope located in La Palma, Canary Islands.

By splitting up Hubble Space Telescope images, researchers find the stellar mass of the bulge of its host galaxy is similar to log(M budge/M○ = 10.92 + 0.07.

[23] An article published in 2021, found out according to observations by ESA's XMM-Newton and NASA's NuSTAR space telescopes, the black hole emits out X-ray flares from the region.

Further analysis by researches showed, brief flashes of photons that are found consistent in the re-emergence of emission, proving they had reverberated from black hole's accretion disk in form light echoes, which are subsequently distorted and extended by the galaxy's strong gravitational field.
