Hydrogen Masers Reveal New Secrets of a Massive Star to ALMA Scientists
While using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the masers around oddball star MWC 349A scientists discovered something unexpected: a previously unseen jet of material launching from the star's gas disk at impossibly high speeds. What's more, they believe the jet is caused by strong magnetic forces surrounding the star. The discovery could help researchers to understand the nature and evolution of massive stars and how hydrogen masers are formed in space. The new observations were presented today in a press conference at the 241st meeting of the American Astronomical Society (AAS) in Seattle, Washington.
Maseres de hidrogeno revelan nuevos secretos de estrella masiva a cientificos de ALMA
Mientras usaba el Atacama Large Millimeter/submillimeter Array (ALMA) para estudiar los maseres presentes alrededor de la inusual estrella MWC 349A, un equipo cientifico descubrio algo inesperado: un desconocido chorro de material emanando del disco de gas de la estrella a velocidades inverosimiles. Se cree, ademas, que el chorro es generado por intensas fuerzas magneticas presentes alrededor de la estrella. El hallazgo podria ayudar a la comunidad cientifica a entender la naturaleza y la evolucion de las estrellas masivas, y entender como los maseres de hidrogeno se forman en el espacio. Las nuevas observaciones se presentaron hoy durante una conferencia de prensa en la asamblea n.o 241 de la Sociedad Astronomica de Estados Unidos (AAS, en su sigla en ingles) en Seattle (Washington, Estados Unidos).
ALMA Scientists Find Pair of Black Holes Dining Together in Nearby Galaxy Merger
While studying a nearby pair of merging galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA)-- an international observatory co-operated by the U.S. National Science Foundation's National Radio Astronomy Observatory (NRAO)-- scientists discovered two supermassive black holes growing simultaneously near the center of the newly coalescing galaxy. These super-hungry giants are the closest together that scientists have ever observed in multiple wavelengths. What's more, the new research reveals that binary black holes and the galaxy mergers that create them may be surprisingly commonplace in the Universe. The results of the new research were published today in The Astrophysical Journal Letters, and presented in a press conference at the 241st meeting of the American Astronomical Society (AAS) in Seattle, Washington.
Equipo cientifico de ALMA detecta pareja de agujeros negros cenando juntos en galaxias cercanas en colision
Mientras estudiaban una dupla de galaxias en colision cercanas con el Atacama Large Millimeter/submillimeter Array (ALMA) --un observatorio internacional coadministrado por el Observatorio Radioastronomico Nacional (NRAO, en su sigla en ingles) de la Fundacion Nacional de Ciencia de Estados Unidos--, un equipo cientifico descubrio dos agujeros negros supermasivos creciendo juntos cerca del centro de la nueva galaxia en ciernes. Es la primera vez que se observa en longitudes de onda multiples a dos mastodontes hambrientos como estos tan cerca el uno del otro. El estudio tambien revelo que los agujeros negros binarios y las galaxias en colision que los originan pueden ser fenomenos sorprendentemente comunes en el Universo. Los resultados de esta investigacion se publicaron hoy en la revista The Astrophysical Journal Letters se presentaron durante una conferencia de prensa en la asamblea n.o 241 de la Sociedad Astronomica de Estados Unidos (AAS, en su sigla en ingles) en Seattle (Washington
ALMA and JWST Reveal Galactic Shock is Shaping Stephan's Quintet in Mysterious Ways
Shockwaves resulting from the violent collision between an intruder galaxy and Stephan's Quintet are helping astronomers to understand how turbulence influences gas in the intergalactic medium. New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) and the James Webb Space Telescope (JWST) have revealed that a sonic boom several times the size of the Milky Way has kickstarted a recycling plant for warm and cold molecular hydrogen gas. What's more, scientists uncovered the break-up of a giant cloud into a fog of warm gas, the possible collision of two clouds forming a splash of warm gas around them, and the formation of a new galaxy. The observations were presented today in a press conference at the 241st meeting of the American Astronomical Society (AAS) in Seattle, Washington.
ALMA y telescopio James Webb revelan que choque galactico incide de formas misteriosas en Quinteto de Stephan
Las ondas de choque generadas por la violenta colision entre una galaxia intrusa y el Quinteto de Stephan estan ayudando a la comunidad astronomica a entender como la turbulencia incide en el gas presente en el medio intergalactico. Las nuevas observaciones realizadas con el Atacama Large Millimeter/submillimeter Array (ALMA) y el telescopio espacial James Webb revelaron que una explosion sonica varias veces mas grande que la Via Lactea dio origen a un proceso de reciclaje de gas de hidrogeno molecular frio y caliente. Tambien se observo la desintegracion de una nube gigante que se convirtio en una niebla de gas caliente, asi como la posible colision de dos nubes que dejaron una mancha de gas caliente a su alrededor y la formacion de una nueva galaxia. Los resultados de estas observaciones se presentaron hoy durante una conferencia de prensa en la asamblea n.o 241 de la Sociedad Astronomica de Estados Unidos (AAS, en su sigla en ingles) en Seattle (Washington, Estados Unidos).

New Type of Entanglement Lets Scientists 'See' Inside Nuclei
Nuclear physicists have found a new way to use the Relativistic Heavy Ion Collider (RHIC)--a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory--to see the shape and details inside atomic nuclei. The method relies on particles of light that surround gold ions as they speed around the collider and a new type of quantum entanglement that's never been seen before.
High-performance Visible-light Lasers that Fit on a Fingertip
Researchers at Columbia Engineering's Lipson Nanophotonics Group have created visible lasers of very pure colors from near-ultraviolet to near-infrared that fit on a fingertip. The colors of the lasers can be precisely tuned and extremely fast - up to 267 petahertz per second, which is critical for applications such as quantum optics. The team is the first to demonstrate chip-scale narrow-linewidth and tunable lasers for colors of light below red -- green, cyan, blue, and violet.
