  • There are galaxies that shouldn’t exist… or should they?: Astronomy Fridays
    2025/04/24

    The James Webb Space Telescope observed for the first time some very, very distant, yet very massive—that is, very “fat”—galaxies. But at that time, the Universe was very young, so young that these galaxies shouldn't have had time to become so “heavy,” based on what we thought we knew about how galaxies form and the history of the Universe. They were called “impossible galaxies,” but are they really?

  • Water is common but rare: “Astronomy Fridays” at UNAM Centro Cultural Morelia
    2025/03/27

    When we talk about a lack of water, we mean fresh water for human consumption, as well as farming and ranching. But in the universe water is in many more places that we can imagine. At the same time, it is a very special substance, even rare, with very different properties compared to others.

    Using JWST near-infrared data of the inner Orion Nebula, Pearson & McCaughrean (2023) detected 40 binary systems they proposed to be Jupiter-Mass Binary Objects (JuMBOs) – although their actual nature is still in debate. Only one of the objects, JuMBO24, was detected by us in the radio continuum. We have used archive as well as new VLA observations to reach the following conclusions: 1) We set an upper limit of ≃ 6 km s−1 to the velocity of the radio source in the plane of the sky. This upper limit favors an origin for this source similar to that of stars, that is, from a stationary contracting core. 2) We searched unsuccessfully at 5 GHz for very compact continuum emission with the High Sensitivity Array (HSA). 3) The nature of the radio emission remains uncertain but the lack of strong variability (all VLA observations are consistent with a steady flux of ∼50 μJy), of detection on long HSA baselines, and of detectable circular polarization in VLA data do not favor a non-thermal origin.

    #1: A dying galaxy triggers the birth of new stars
    2022/01/30

    What caused our Sun to be born? A recent paper by researchers from the Instituto de Radioastronomía y Astrofísica (IRyA) suggests that the answer may lie in a small satellite galaxy that is slowly being devoured by our larger Milky Way Galaxy.
