Source-derived summary

PKS 0346−27 is a blazar located in the constellation of Fornax. Its redshift is (z) 0.991 and as such lies at a distance of 7.8 billion light-years from Earth. This object is also classified as a flat-spectrum radio quasar with its radio spectrum seeming to appear flat with its radio source being first identified in 1966 by astronomers.

Description

PKS 0346−27 is highly active on the electromagnetic spectrum in terms of emission of gamma-rays, although it can be categorized as a Low-Synchrotron-Peaked Blazar during its quiescent period because of the low spectral energy distribution peak. On February 2, 2018, it was shown to be in a high-flux state with its gamma-ray flux reaching levels of 1.0 ± 0.2 × 10−6 photons cm−2 s-1 upon detection by Fermi Gamma-ray Space Telescope. The next time the object displayed immense activity, was on April 24, 2019, where it reached a new historic high gamma-ray flux level of 3.2 ± 0.3 × 10−6 photons cm−2 s−1. Subsequently, it displayed more renewed activity recorded in February 2020 and on November 24, 2021. An optical flare was also observed, in addition to gamma-rays where the object brightened in brightness.

Because of its powerful activity, PKS 0346−27 has been studied in detail. Data from a multiwavelength temporal and spectral study showed the object had multiple flaring episodes based on its gamma-ray light curve analysis from data collected over more than 2 years, with its minimum variability time estimated as 1.34 ± 0.3 days, indicating the source of PKS 0346−27 is compact.

Editorial summary

“PKS 0346−27” enters the record as quasar in the constellation Fornax. Crown Archives preserves that source wording while asking what quasar, constellation and Fornax can confirm, complicate or overturn.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1966, 2018, 2019, 2020—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around quasar, constellation and Fornax.
Editorial analysis

Why this record matters

“PKS 0346−27” is worth following because a concise public description often conceals a longer documentary argument. Here, quasar, constellation and Fornax provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q86370634. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1966, 2018, 2019 and 2020.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
