Scientists Observe Gas Re-accretion in Dying Galaxies for the First Time

A new study from scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) suggests that previously displaced gases can re-accrete onto galaxies, potentially slowing down the process of galaxy death caused by ram pressure stripping, and creating unique structures more resistant to its effects.

Científicos observan por primera vez reacreción de gas en galaxias moribundas

Un nuevo estudio realizado con datos del Atacama Large Millimeter/submillimeter Array (ALMA) postula que nubes de gas previamente desplazadas pueden volver a acumularse y formar nuevas galaxias mediante acreción, ralentizando de esa forma el proceso de despojo por presión que causa la extinción de las galaxias y creando estructuras únicas más resistentes a dicho fenómeno.

No olviden el surco: científicos usan masa estelar para establecer vínculo entre exoplanetas y discos protoplanetarios

A partir de los datos de más de 500 estrellas jóvenes observadas con el Atacama Large Millimeter/Submillimeter Array (ALMA), los científicos descubrieron un vínculo directo entre las estructuras de los discos protoplanetarios (los discos que rodean a las estrellas y donde se forman planetas nuevos) y las características demográficas de los planetas que allí nacen.

Mind the Gap: Scientists Use Stellar Mass to Link Exoplanets to Planet-Forming Disks

Data from 500 young stars observed with the Atacama Large Millimeter/submilliter Array (ALMA) is giving scientists a window back through time, allowing them to predict what exoplanetary systems looked like through each stage of their formation. And it all starts with a link between higher mass stars, disks with gaps in them, and a high occurrence of observed exoplanets.

Study of Young Chaotic Star System Reveals Planet Formation Secrets

A team of scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the young star Elias 2-27 have confirmed that gravitational instabilities play a key role in planet formation, and have for the first time directly measured the mass of protoplanetary disks using gas velocity data, potentially unlocking one of the mysteries of planet formation.

Cosmic cartographers map the nearby Universe revealing the diversity of star-forming galaxies

A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has completed the first census of molecular clouds in the nearby Universe. The study produced the first images of nearby galaxies with the same sharpness and quality as optical imaging and revealed that stellar nurseries do not all look and act the same. In fact, they’re as diverse as the people, homes, neighborhoods, and regions that make up our own world.

Record-breaking stellar flare from nearby star recorded in multiple wavelengths for the first time

Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) observed a record-breaking stellar flare from Proxima Centauri. The study also marks the first time that a powerful stellar flare, other than those from the Sun, has been observed with such complete wavelength coverage.

Discovery points to origin of mysterious ultraviolet radiation

Lyman-alpha blobs (LABs) are gigantic clouds of hydrogen gas that produce ultraviolet light known as Lyman-alpha emissions. A study of Lyman-alpha blob 6 (LAB-6) is the first LAB with infalling gas feature. The findings suggest that star-forming galaxies are likely the primary energy source of Lyman-alpha radiation emitted from LAB-6.
