The evidence comes from combined observations made with the James Webb Space Telescope (JWST<\/a>) and ground-based follow-up at the W. M. Keck Observatory<\/a> on Mauna Kea, Hawai\u02bbi, which together capture the unusual system now known as the Infinity galaxy.<\/p>\n Images showed two compact red nuclei and overlapping rings, giving the object an infinity-symbol outline.<\/p>\n The work was led by Prof. Pieter van Dokkum at Yale University<\/a>\u00a0 in New Haven, Connecticut. His research focuses on how galaxies assemble their stars and dark matter, so rare mergers can test black hole ideas.<\/p>\n Two galaxies collide<\/p>\n A near head-on crash between two disk galaxies can push stars outward, leaving expanding loops around each surviving core.<\/p>\n Gravity from the impact pulls and compresses the disks, and the disturbed material moves in waves that trace loops.<\/p>\n Because the geometry must line up just right, the Infinity galaxy<\/a> is a rare case rather than a common stage.<\/p>\n Keck\u2019s spectrograph spread the galaxy\u2019s light into many narrow features, letting researchers measure its distance with precision.<\/p>\n Those features gave a redshift<\/a>, a measure of how much light is stretched, placing the Infinity galaxy at z = 1.14.<\/p>\n With that distance secured, the team could track how gas<\/a> and the black hole move relative to each other.<\/p>\n Finding the hidden center<\/p>\n A supermassive black hole usually sits in a galaxy\u2019s nucleus, but the Infinity galaxy shows the brightest source between two nuclei.<\/p>\n Radio maps from the Very Large Array and X-ray counts from Chandra matched the same spot in glowing gas.<\/p>\n \u201cHow can we make sense of this?\u201d said Prof. Dokkum, after the black hole appeared in the middle.<\/p>\n Bright emission lines in the Keck spectrum showed that a compact energy source is heating nearby gas.<\/p>\n That accretion, gas<\/a> falling inward and heating as it compresses, can light up space even when stars stay quiet.<\/p>\n Strong line emission also means the black hole\u2019s mass estimate depends on assumptions about how feeding power scales with mass.<\/p>\n Gas stripped of electrons<\/p>\n Infrared images highlighted a cloud of glowing material wrapped around the midpoint between the two compact galaxy<\/a> cores.<\/p>\n The cloud is ionized gas, gas whose electrons have been stripped away, so hydrogen shines in sharp emission lines.<\/p>\n Because the brightest glow surrounds the central source, the gas map becomes a clue about where the black hole formed.<\/p>\n Collision forces can slam gas clouds together, raising density and turbulence in a way that favors runaway collapse.<\/p>\n \u201cThis compression might just be enough to form a dense knot, which then collapsed into a black hole,\u201d said Prof. Dokkum.<\/p>\n If that scenario holds up, it would show black holes can start outside galactic centers under extreme pressure.<\/p>\n Small seeds from stars<\/p>\n One common idea is light seeds, small black holes born from dying stars, which later grow by feeding and merging.<\/p>\n Each seed begins small, so the path demands long stretches of accretion or repeated black hole mergers inside crowded galaxies.<\/p>\n That slow build becomes hardest when the universe is young, because less time is available for compounding growth.<\/p>\n A competing pathway is heavy seeds<\/a>, black holes born large from collapsing gas clouds, which can grow into giants quickly.<\/p>\n For this to happen, heating and turbulence must keep the gas from breaking into many stars while it falls inward.<\/p>\n The same requirement makes the idea hard to test, because it depends on conditions that are rare and brief.<\/p>\n Why dense gas matters<\/p>\n Extreme gas densities were likely more common when galaxies first assembled, even if collisions like the Infinity galaxy remain unusual today.<\/p>\n Dense, turbulent gas can resist normal star formation, which lets gravity gather mass into one compact object instead.<\/p>\n That is why a later-era merger matters, because it offers a nearby check on physics often linked to the early universe.<\/p>\n Alternative explanations include a black hole kicked from a galaxy center or a faint third galaxy hiding in the same line.<\/p>\n A key test compares the black hole\u2019s speed to the surrounding gas, expecting agreement within 30 miles per second.<\/p>\n Close matching would strengthen the case for birth on site, but even that cannot show the first moments directly.<\/p>\n Next observations with sharp optics<\/p>\n Higher-resolution observations can probe the gas closest to the black hole, where gravity should dominate over large-scale collision flows.<\/p>\n Keck will use adaptive optics, mirrors that rapidly correct blurring from Earth\u2019s air, to sharpen the view of the core.<\/p>\n If the gas shows rotation, outflows, or shocks near the center, those patterns could rule out some birth scenarios.<\/p>\n Supermassive black hole lessons<\/p>\n Computer simulations can replay the collision with physics turned on, tracking how gas cools, fragments, and falls under gravity.<\/p>\n Modelers must include star formation, feedback, and turbulence, because each can steal gas or keep it bound into one clump.<\/p>\n A convincing match would make the Infinity galaxy a guide for future searches, but a mismatch would demand other explanations.<\/p>\n Together, Webb imaging and multi-wavelength follow-up point to a young black hole embedded in gas shaped by a rare merger.<\/p>\n Confirming true birth will require sharper spectra and realistic simulations, yet the case already widens how black holes might begin.<\/p>\n The study is published in The Astrophysical Journal
