F200DB-045
Observation data (J2000 epoch)
Constellation Volans
Right ascension 07h 23m 22.770s [1]
Declination −73° 27 39.72 [1]
Redshift 20.4 [2] [3]

F200DB-045 is a candidate high-redshift galaxy, with an estimated redshift of approximately z = 20.4, [2] [3] corresponding to 168 million years after the Big Bang. [4] If confirmed, it would be one of the earliest and most distant known galaxies observed.

Contents

F200DB-045 would have a light-travel distance (lookback time) of 13.7 billion years, and, due to the expansion of the universe, a present proper distance of 36.1 billion light-years. [4]

Nonetheless, the redshift value of the galaxy presented by the procedure in one study [2] may differ from the values presented in other studies using different procedures. [3] [5]

Discovery

The candidate high-redshift galaxy F200DB-045 was discovered within the data from the Early Release Observations (ERO) that was obtained using the Near Infrared Camera of the James Webb Space Telescope (JWST) in July 2022. This data included a nearby galaxy cluster SMACS J0723.3–7327, a massive cluster known as a possible "cosmic telescope" in amplifying background galaxies, including the F200DB-045 background galaxy. [2] [3]

Distance

Only a photometric redshift has been determined for F200DB-045; follow-up spectroscopic measurements will be required to confirm the redshift (see spectroscopic redshift). Spectroscopy could also determine the chemical composition, size and temperature of the galaxy.

If confirmed, the galaxy may have existed in its star formation phase in the early universe, when it would have been composed mostly of dust as well as young and massive population III stars.

UDFj-39546284 is a high-redshift Lyman-break galaxy discovered by the Hubble Space Telescope in infrared Hubble Ultra-Deep Field (HUDF) observations in 2009. The object, located in the Fornax constellation, was identified by G. Illingworth, R. Bouwens and the HUDF09 Team during 2009 and 2010. It was reported with a redshift of z~10 using Hubble and Spitzer Space Telescope photometric data, with later reports in 2012 suggesting a possibly higher redshift of z = 11.9 Although doubts were raised that this galaxy could instead be a low-redshift interloper with extreme spectral emission lines producing the appearance of a very high redshift source, later spectroscopic observations by the James Webb Space Telescope's NIRSpec instrument in 2022 confirmed the galaxy's high redshift to a spectroscopically confirmed estimate of z = 11.58.

El Gordo (lit. The Fat One) (ACT-CL J0102-4915 or SPT-CL J0102-4915) is the largest distant galaxy cluster observed at its distance or beyond, as of 2011. As of 2014, it held the record for being the largest distant galaxy cluster to have been discovered with a mass of slightly less than three quadrillion solar masses although later its mass was reduced to about 2.1×1015 (2.1 quadrillion) solar masses with a 10% uncertainty. It was found by NASA's Chandra X-ray Observatory, the Atacama Cosmology Telescope (funded by the National Science Foundation) and the European Southern Observatory's Very Large Telescope.

<i>Webbs First Deep Field</i> First operational image from NASAs James Webb Space Telescope

Webb's First Deep Field is the first operational image taken by the James Webb Space Telescope (JWST). The deep-field photograph, which covers a tiny area of sky visible from the Southern Hemisphere, is centered on SMACS 0723, a galaxy cluster in the constellation of Volans. Thousands of galaxies are visible in the image, some as old as 13 billion years. It is the highest-resolution image of the early universe ever taken. Captured by the telescope's Near-Infrared Camera (NIRCam), the image was revealed to the public by NASA on 11 July 2022.

SMACS J0723.3–7327, commonly referred to as SMACS 0723, is a galaxy cluster about 4 billion light years from Earth, within the southern constellation of Volans. It is a patch of sky visible from the Southern Hemisphere on Earth and often observed by the Hubble Space Telescope and other telescopes in search of the deep past. It was the target of the first full-color image to be unveiled by the James Webb Space Telescope (JWST), imaged using NIRCam, with spectra included, showing objects lensed by the cluster with redshifts implying they are 13.1 billion years old. The cluster has been previously observed by the Hubble Space Telescope (HST) as part of the Southern MAssive Cluster Survey (SMACS), as well as Planck and Chandra.

GLASS-z12 is a Lyman-break galaxy discovered by the Grism Lens-Amplified Survey from Space (GLASS) observing program using the James Webb Space Telescope's NIRCam in July 2022. Spectroscopic observations of GLASS-z12 by the Atacama Large Millimeter Array (ALMA) in August 2022 confirmed that the galaxy has a spectroscopic redshift of 12.117±0.012, making it one of the earliest and most distant galaxies ever discovered, dating back to just 350 million years after the Big Bang, 13.6 billion years ago. ALMA observations detected an emission line associated with doubly ionized oxygen at 258.7 GHz with a significance of 5σ, suggesting that there is very low dust content in GLASS-z12, if not the early universe as well. Also based on oxygen-related measurements, the age of the galaxy is confirmed.

JADES-GS-z13-0 is a high-redshift Lyman-break galaxy discovered by the James Webb Space Telescope (JWST) during NIRCam imaging for the JWST Advanced Deep Extragalactic Survey (JADES) on 29 September 2022. Spectroscopic observations by JWST's NIRSpec instrument in October 2022 confirmed the galaxy's redshift of z = 13.2 to a high accuracy, establishing it as the oldest and most distant spectroscopically-confirmed galaxy at the time, with a light-travel distance of 13.4 billion years. Due to the expansion of the universe, its present proper distance is approximately 33 billion light-years. In 2024, two older and more distant galaxies, JADES-GS-z14-0 and JADES-GS-z14-1, were found.

SN H0pe (pronounced: Supernova Hope) is a Type Ia supernova discovered in 2023, at a redshift of z=1.78. It is a supernova discovered in a gravitationally lensed subject system, being itself a triply lensed object. Its name, H0pe, comes from its proposed utility in determination of the Hubble Constant (H0) that would allow determination of H0 in the distant universe and compare it with local determinations; and hopefully resolve Hubble tension, the difference in such determinations with local Type Ia supernovae and those based on the very distant Cosmic Microwave Background. The supernova exploded when the universe was 3.5 billion years old, rather than at today's date of 13.8 billion years old. The supernova progenitor was a white dwarf star, the progenitor of all Type Ia supernovae. The gravitational lens is galaxy cluster PLCK G165.7+67.0 (at a redshift of z=0.35), which lensed the supernova and its host galaxy.

UHZ1 is a background galaxy containing a quasar. At a redshift of approximately 10.1, UHZ1 is at a distance of 13.2 billion light-years, seen when our universe was about 3 percent of its current age. This redshift made it the most distant, and therefore earliest known quasar in the observable universe as of 2023. To detect this object, astronomers working at the Chandra X-ray Observatory used the Abell 2744's cluster mass as a gravitational lens in order to magnify distant objects directly behind it. At the time of discovery, it exceeded the distance record of QSO J0313−1806.
