Nombran director en proyecto global del EHT de la UNAM

Nombramiento internacional y liderazgo científico impulsaron al investigador mexicano.

El investigador Laurent Loinard del Instituto de Radioastronomía y Astrofísica (Irya) de la Universidad Nacional Autónoma de México (UNAM) fue nombrado director de Proyecto del consorcio del Telescopio del Horizonte de Eventos (EHT), decisión que lo colocó al frente de una de las colaboraciones científicas más influyentes del mundo.

La designación consolidó su trayectoria en interferometría de larga línea de base desarrollada durante décadas en la Unam, campus Morelia. Autoridades académicas señalaron que la resolución reflejó la confianza de los representantes de las instituciones participantes en el trabajo del investigador mexicano.

El director del Irya, Luis Alberto Zapata González, señaló que la nueva responsabilidad fue un reconocimiento al trabajo acumulado por Laurent Loinard en la colaboración del EHT. Resaltó que su trayectoria en el estudio de estructuras astronómicas mediante técnicas de interferometría aportó resultados sólidos a la comunidad internacional. Informó que el nombramiento fue recibido con respaldo institucional por parte de la Unam y de su comunidad científica.

Cooperación internacional

El pasado 1 de noviembre, Laurent Loinard fue designado para dirigir la colaboración internacional que en 2019 publicó la primera imagen de un agujero negro supermasivo. La decisión fue formalizada por la Junta de la Colaboración, integrada por directores de trece instituciones que forman parte del EHT. El investigador explicó que la resolución siguió un proceso interno de selección establecido por el consorcio.

La designación inicial de Laurent Loinard fue establecida por un periodo de nueve meses debido a la renuncia del director anterior. El investigador cubrirá el resto del mandato con la posibilidad de ser ratificado por un periodo adicional de dos años, conforme a las reglas internas de la colaboración. Indicó que la renovación dependerá de la evaluación que realicen los representantes de las instituciones miembro.

El científico afirmó que el nombramiento posicionó a la Unam, al Irya y a México en un lugar central dentro de uno de los proyectos más relevantes de la astrofísica mundial. Añadió que la colaboración EHT ha mantenido una amplia visibilidad en la comunidad académica y en espacios de educación, cultura y divulgación científica. Explicó que el trabajo conjunto ha permitido ampliar el conocimiento sobre los entornos extremos de los agujeros negros.

Retos del EHT

Laurent Loinard puntualizó que la colaboración enfrentó grandes expectativas tras obtener resultados históricos durante la última década. Mencionó que las primeras imágenes de los agujeros negros en la galaxia M87 y en el centro de la Vía Láctea consolidaron al EHT como un referente científico. Explicó que las próximas metas incluyen obtener secuencias de imágenes que permitirían crear las primeras películas de agujeros negros.

El investigador señaló que la colaboración busca comprender de manera más amplia la relación entre los agujeros negros supermasivos y los chorros de gas energético que emergen de su entorno inmediato. Explicó que esta línea de investigación requiere capacidades de observación coordinadas en diversos puntos del planeta. Detalló que el EHT integró expertos de alrededor de veinte países y cerca de cuatrocientas personas especializadas en astrofísica, ingeniería y cómputo. –sn–

Tour:
A New Panorama of Our Galactic Center

A new panorama from NASA's Chandra X-ray Observatory and the MeerKAT radio telescope provides a stunning view of the center of our Milky Way galaxy. It also reveals threads of superheated gas and magnetic fields, which are weaving a tapestry of energy near the supermassive black hole that resides there.

Over the course of its mission, Chandra has taken many observations of the Galactic Center. This latest expands Chandra's high-energy view farther above and below the plane of the galaxy — that is, the disk where most of the galaxy's stars reside — than previous imaging campaigns. In the image, we see X-rays with different energies from Chandra in different colors. These have been combined with radio data from MeerKAT, a radio telescope in South Africa.

The result is intricate to the eye and also contains a wealth of scientific information to explore. For example, researchers identified long and narrow bands of X-rays that they call "threads". These features are bound together by thin strips of magnetic fields. One of these threads points perpendicular to the plane of the galaxy and is about 20 light-years long but only one-hundredth that size in width. (That's about five times the distance between the Sun and the nearest star.) These threads may have formed when magnetic fields aligned in different directions, collided, and became twisted around each other in a process called magnetic reconnection. This is similar to the phenomenon that drives energetic particles away from the Sun and is responsible for the space weather that sometimes affects Earth.

A detailed study of these threads teaches us more about the galactic space weather astronomers have witnessed throughout the region.

Explanation:
What's going on near the center of our galaxy? To help find out, a newly detailed panorama has been composed that explores regions just above and below the galactic plane in radio and X-ray light. X-ray light taken by the orbiting Chandra Observatory is shown in orange (hot), green (hotter), and purple (hottest) and superposed with a highly detailed image in radio waves, shown in gray, acquired by the MeerKAT array. Interactions are numerous and complex. Galactic beasts such as expanding supernova remnants, hot winds from newly formed stars, unusually strong and colliding magnetic fields, and a central supermassive black hole are all battling in a space only 1000 light years across. Thin bright stripes appear to result from twisting and newly connecting magnetic fields in colliding regions, creating an energetic type of inner galactic space weather with similarities to that created by our Sun. Continued observations and study hold promise to not only shed more light on the history and evolution of our own galaxy -- but all galaxies.

Today in Egg Harbor Township, New Jersey, USA, there was a protest/rally to oppose the proposed cuts to the Veterans Administration by the Trump regime.

More than 83,000 employees are expected to be cut. Essential programs are scheduled to be eliminated. We were there today to fight for the rights of those who have fought for us.

This image shows the region around the Milky Way's central supermassive black hole, known as Sagittarius A* (Sgr A*), in infrared (orange and purple) and X-ray light (blue). The image is scanned from left to right and the data are transformed into sound. The brightness of the objects is represented by the volume, while the vertical positions of the sources in the image are mapped to musical pitches. X-rays are played with a soft synthesizer and the infrared data are heard as bass notes and plucked sounds. The brightest region in the middle of the image (and hence the loudest) is where Sgr A* the black hole, resides. It is within this area that the Event Horizon Telescope was able to peer to obtain the first image of Sgr A* itself.

About the Sound:

The image is scanned from left to right with brightness controlling the volume.

The vertical position is mapped to musical pitches with higher pitches toward the top.

The mid-IR layer is limited to a low range and played on a bass.

The X-ray layer is limited to a high range and played on a soft synth.

The brightest regions in the X-ray image (including Sgr A*) are highlighted by increasing the brightness of the synth's sound.

Listen for a peak at the location of the supermassive black hole Sagittarius A* at the 14 second mark.

The near IR layer covers the full pitch range.

The stars visible in the near-IR image are played on a plucked distorted synth.

The stereo pan follows the scan from left to right.
