Filamentos estelares fantasmales capturados con la imagen de DECam más grande jamás publicada

Con la poderosa Cámara de Energía Oscura (DECam por sus siglas en inglés) de 570 megapíxeles, fabricada por el Departamento de Energía de Estados Unidos, los astrónomos han construido una imagen gigante de 1,3 gigapíxeles que muestra la parte central del remanente de Supernova Vela, un cadáver cósmico de una gigantesca estrella que explotó como una supernova. DECam es uno de los instrumentos de imágenes de campo amplio más productivos del mundo y está montada en el Telescopio de 4 metros Víctor M. Blanco de la Fundación Nacional de Ciencias de EE.UU en el Observatorio Interamericano Cerro Tololo en Chile, un Programa de NOIRLab de NSF.

Ghostly Stellar Tendrils Captured in Largest DECam Image Ever Released

With the powerful, 570-megapixel Department of Energy-fabricated Dark Energy Camera (DECam), astronomers have constructed a massive 1.3-gigapixel image showcasing the central part of the Vela Supernova Remnant, the cosmic corpse of a gigantic star that exploded as a supernova.

The ‘Brightest of All Time’ Gamma-Ray Burst and Its Ordinary Supernova

A team of astronomers using the Gemini South telescope, one half of the International Gemini Observatory operated by NSF’s NOIRLab, have observed the ‘brightest of all time’ long gamma-ray burst. Using the Gemini South Multi-Object Spectrograph (GMOS), the team found that although GRB 221009A exhibits a jet structure as rare as it is bright, its associated supernova is surprisingly ordinary.

La explosión de rayos gamma “más brillante de todos los tiempos”

Un equipo de astrónomos observó la explosión de rayos gamma “más brillante de todos los tiempos” con el telescopio Gemini Sur, la mitad austral del Observatorio Internacional Gemini que opera NOIRLab de NSF. Gracias al Espectrógrafo Multi Objetos de Gemini Sur (GMOS por sus siglas en inglés), el equipo descubrió que, a pesar que GRB 221009A presentaba una estructura de jet tan inusual como su brillo, su supernova no era nada fuera de lo común.

Desde Chile identifican una futura Kilonova

Utilizando datos del telescopio SMARTS de 1,5 metros ubicado en Cerro Tololo, un programa de NOIRLab de NSF y Observatorio AURA, un equipo de astrónomos descubrió un sistema estelar que en el futuro formará una kilonova, es decir una explosión ultra poderosa, generadora de oro, que se produce por la fusión de estrellas de neutrón. Este tipo de sistemas estelares son tan inusuales que se cree que existen apenas cerca de 10 en toda la Vía Láctea.

First Kilonova Progenitor System Identified

Astronomers using data from the SMARTS 1.5-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO), a Program of NSF’s NOIRLab, have made the first confirmed detection of a star system that will one day form a kilonova — the ultra-powerful, gold-producing explosion created by merging neutron stars. These systems are so phenomenally rare that only about 10 such systems are thought to exist in the entire Milky Way.

Media Tip: Scientists use Argonne accelerator to study star-like environment created during National Ignition Facility laser shots

The recent achievement of fusion ignition at the National Ignition Facility (NIF) marks a monumental scientific step in controlling the physics involved in the quest for future limitless clean energy.

Deep-Space Discovery: Oddball Gamma-Ray Burst Forces Revision of Theoretical Framework

In the Dec. 7 issue of the journal Nature, an international team of astrophysicists report the discovery of a unique cosmological gamma-ray burst (GRB) that defies prevailing theories of how the violent cosmic explosions form.

Kilonova Discovery Challenges our Understanding of Gamma-Ray Bursts

While studying the aftermath of a long gamma-ray burst (GRB), two independent teams of astronomers using a host of telescopes in space and on Earth, including the Gemini North telescope on Hawai‘i and the Gemini South telescope in Chile, have uncovered the unexpected hallmarks of a kilonova, the colossal explosion triggered by colliding neutron stars. This discovery challenges the prevailing theory that long GRBs exclusively come from supernovae, the end-of-life explosions of massive stars.

Oxygen Formation in the Light of Gamma Beams

Nuclear fusion reactions in stars consume carbon-12 to produce oxygen-16, and the resulting ratio of carbon to oxygen shapes a star’s evolution. Physicists have not been able to measure this ratio with precision using existing experimental methods. A new method shines gamma beams on an oxygen-16 target and captures images of the outgoing reaction products to obtain higher-quality data on this reaction.

Rutgers Expert Available to Discuss Supernova Discovery

New Brunswick, N.J. (April 21, 2021) – Rutgers University–New Brunswick astrophysicist John P. (Jack) Hughes is available for interviews on a supernova (exploding star) discovery published today in the journal Nature. The discovery, made with NASA’s Chandra X-ray Observatory, features…

NOvA turns its eyes to the skies

The NOvA experiment, best known for its measurements of neutrino oscillations using particle beams from Fermilab accelerators, has been turning its attention to measurements of cosmic phenomena. In a series of results, NOvA reports on neutrinos from supernovae, gravitational-wave events from black hole mergers, muons from cosmic rays, and its search for the elusive monopole.

Searching for supernova neutrinos with DUNE

The international Deep Underground Neutrino Experiment collaboration has published a paper about its capability for performing supernova physics. It details the kind of activity DUNE expects in the detector during a supernova burst, how DUNE will know once a supernova occurs and what physics DUNE will extract from the neutrinos. DUNE’s unique strength is its sensitivity to a particular type of neutrino called the electron neutrino, which will provide scientists with supernova data not available from any other experiment.

New NSF Physics Frontier Center Will Focus on Neutron Star Modeling in ‘Gravitational Wave Era’

A new Physics Frontier Center at UC Berkeley, supported by the National Science Foundation, expands the reach and depth of existing capabilities on campus and at neighboring Berkeley Lab in modeling one of the most violent events in the universe: the merger of neutron stars and its explosive aftermath.

Lab-Created Shock Waves Mimic Supernova Particle Accelerators

When stars explode as supernovas, they produce shock waves in the plasma that blast cosmic rays into the universe at relativistic speeds. How exactly they do that remains a mystery. New experiments using powerful lasers have recreated a miniature version of these supernova shocks in the lab, where scientists can observe how they accelerate particles.

Supergiant Atmosphere of Antares Revealed by Radio Telescopes

An international team of astronomers has created the most detailed map yet of the atmosphere of the red supergiant star Antares. The unprecedented sensitivity and resolution of both the Atacama Large Millimeter/submillimeter Array (ALMA) and the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) revealed the size and temperature of Antares’ atmosphere from just above the star’s surface, throughout its chromosphere, and all the way out to the wind region.

How to Build a 3D Map of the Universe – and Why

In the 1980s, Saul Perlmutter at the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (LBNL) and his collaborators realized that they could use data about supernovae to research the history of the universe. They expected to see that very distant supernovae appear a bit brighter than they would in an expanding universe that wasn’t slowing in its growth.

The data revealed something else entirely.

Automated Observing Network Inaugurated at SOAR Telescope

To provide astronomers with a network of world-class telescopes that can be accessed with a touch of a button, four ground-based astronomical observatories have joined forces to set up the Astronomical Event Observatory Network (AEON): Las Cumbres Observatory (LCO), the National Science Foundation’s National Optical Astronomy Observatory (NOAO), the SOAR Telescope, and Gemini Observatory. With AEON, astronomers will be able to automatically follow up on their astronomical objects of interest, with a range of 0.4-meter to 8-meter telescopes, observing in UV light to infrared.
