An international collaboration called exoALMA is using our telescopes to s peer through the dusty disks where planets are born. Thanks to their newly developed advanced imaging techniques, exoALMA has revealed the most sharp images of young solar systems, as never seen before. This research project has just published 17 papers, with several more coming on the several months.

The exoALMA collaboration is using ALMA to conduct a comprehensive planet hunting campaign in the sub-mm regime. They claim to be the first to focus on still-forming planets, instead of fully formed ones.

Unlike traditional planet-hunting methods that look for a young planet's direct light, exoALMA looks for the effects planets have on their surroundings. This approach potentially allows to detect much younger planets than ever before. "It's like trying to spot a fish by looking for ripples in a pond, rather than [the] fish itself.”

Protoplanetary disks from #ALMA.

Though we have learned much about #exoplanets, there is still much we do not know about the steps of planet formation and the precise cosmic recipes that spawn the wide array of planetary bodies we have already uncovered.

Astronomers have conducted one of the deepest surveys ever of #protoplanetary disks, the planet-forming dust belts around young #stars.

The disks are as diverse as are the forming planetary systems.

A Alimentação Carnívora e o Vegetarianismo

A preferência pela alimentação vegetariana, no Oriente, fundamenta-se na perfeita convicção de que, à medida que a alma progride, é necessário, também, que o vestuário de carne se lhe harmonize ao progresso espiritual já alcançado. Mesmo nos remos inferiores, a nutrição varia conforme a delicadeza e sensibilidade dasespécies.

EHT Reveals New Insights of Jets from Supermassive Black Holes. ALMA is a big part of EHT, and in this case provided the most accurate calibration for the observations, which was used later for the longer baselines between EHT telescopes.

ps. IAA-CSIC plays a strong role in EHT and this news, and is where I got my Ph.D., so this is doubly important for me.

BTW, did I mention ALMA is now officially 12 years old? On March 13th, 2013, ALMA was famously commanded by then President Sebastián Piñera to point to the galactic center!

Since then, ALMA has been delivering stunning science year after year, and during Cycle 10 we managed to provide more than 4250 hours of quality data to our Principal Investigators, our highest number ever!

ALMA Discovers “Space Tornadoes” Around the Milky Way’s Core!

Although the galaxy’s central molecular zone (CMZ) has long been known to be filled with swirling dust and gas molecules cycling through formation and destruction, the mechanism that drives this process has remained elusive. Molecules serve as tracers for various processes in molecular clouds, with silicon monoxide (SiO) particularly useful in detecting the presence of shock waves.

Using ALMA’s high resolution and sensitivity to map distinct spectral lines within the molecular clouds at the center of the Milky Way, the team led by Kai Yang (Shanghai Jiao Tong University) has delineated a new type of long, narrow filamentary structure at a significantly finer scale. The dynamic interaction between this turbulent environment and the slim filaments produced as shocks ripple through provides a more complete view of the cyclical processes within the CMZ.

Yang’s team reports it remains unknown how these slim filaments initially arise, but shock processes emerge as a likely explanation.

Galaxy clusters are the largest structures in the universe. Protoclusters like SPT2349-56 offer a unique window into this process, allowing astronomers to observe galaxies as they come together in a dense environment.

By comparing ALMA's high-resolution configuration observations with lower-resolution data from ALMA's Compact Array (ACA), and APEX, the team found a significant amount of molecular gas "invisible" in the higher-resolution ALMA images. The ACA detected 75% more CO than the sum of individual sources detected in higher-resolution ALMA data.

This missing gas isn't just a few faint, undetected galaxies. Instead, it appears to be a diffuse reservoir of gas spread throughout the protocluster.

This hidden gas reservoir could be the key to understanding the intense star formation activity observed in SPT2349-56. The presence of so much extra gas extends the star formation fuel, meaning the overall depletion timescale will exceed 400 million years.

SPT2349-56 is an extreme system, producing stars 10.000 times faster than our Milky Way, and these observations have pushed scientists' understanding of galaxy formation and evolution. No simulation or galaxy formation model had previously predicted this overdensity of gas. These findings also suggest that high-resolution ALMA observations, while excellent for studying individual galaxies, may miss a significant gas component in these early clusters. The missing gas may reside in the circum-galactic medium (CGM) or the pre-heated proto-intracluster medium (proto-ICM).

ALMAGAL, the #ALMA evolutionary study of high-mass protocluster formation in the Galaxy - Presentation of the survey and early results / ALMA data processing and pipeline / Compact source catalog - fragmentation statistics and physical evolution of the core population: arxiv.org/abs/2503.05555 / arxiv.org/abs/2503.05559 / arxiv.org/abs/2503.05663 -> Researchers investigate the ‘recipes’ of star formation: uni-koeln.de/en/university/new - a statistically relevant study of the different formation processes.

arXiv.orgALMAGAL I. The ALMA evolutionary study of high-mass protocluster formation in the Galaxy. Presentation of the survey and early resultsFundamental questions about the physics responsible for fragmenting molecular parsec-scale clumps into cores of ~1000 au are still open, that only a statistically significant investigation with ALMA is able to address: what are the dominant agents that determine the core demographics, mass, and spatial distribution as a function of the physical properties of the hosting clumps, their evolutionary stage and the different Galactic environments in which they reside? To what extent extent is fragmentation driven by clumps dynamics or mass transport in filaments? With ALMAGAL we observed the 1.38 mm continuum and lines toward more than 1000 dense clumps in our Galaxy, with M>500M_sun, surface density > 0.1 g/cm2 and d<7.5 kpc. The ACA and two 12-m array setups were used to deliver a minimum resolution of ~1000 au over the entire sample distance range. The sample covers all evolutionary stages from infrared dark clouds (IRDCs) to HII regions from the tip of the Galactic bar to the outskirts of the Galaxy. The spectral setup includes several molecular lines to trace the multiscale physics and dynamics of gas, notably CH3CN, H2CO, SiO, CH3OH, DCN, HC3N, SO etc. We present an initial overview of the observations and the early science product and results, with a first characterization of the morphological properties of the continuum emission. We use "perimeter-versus-area" and convex hull-versus-area metrics to classify the different morphologies. More extended and morphologically complex shapes are found toward clumps that are relatively more evolved and have higher surface densities.
