Including stellar surface magnetism in models of limb darkening resolves an outstanding discrepancy with observations. This enables improved characterization of transiting exoplanets and a method for measuring stellar magnetization. Kostogryz et al.: nature.com/articles/s4155…

What a wonderful era we live in: watching a total eclipse from Mexico via @NASA while my dear friend @erajpg explains it via @NSF (including polarimetry and magnetic fields explanations!)

@imartividal @pcoffeebreak Gracias!

@Enloro @pcoffeebreak Usamos ángulos de polarización, pero los graficamos mediante gradientes de intensidad. Básicamente, usamos la imagen de las lineas a modo de máscara, por la que hacemos pasar la imagen de intensidad total. Es un poco lioso explicarlo en unos pocos tweets!😜

Lo prometido es deuda. Tal y como discutimos ayer en @pcoffeebreak, aquí tenéis el código para hacer "windplots" al estilo del EHT. Incluyo ejemplo con una imagen sintética. ¡Que lo disfrutéis! (NOTA: habrá algún bug, tras convertirlo en módulo de Python). github.com/marti-vidal-i/…

@imartividal @pcoffeebreak Usaron gradientes de intensidad? Interesante, tengo que ver el código. Normalmente se usan los ángulos de polarization que son los que dan la orientation del Bfield.

@Enloro @pcoffeebreak En este caso, las líneas se muestran como cambios de brillo (contraste) proporcionales a la intensidad de polarización. Eso nos permite añadir cortes al ruido (=lineas de contraste nulo). No sé si habrá versión de LIC que actúe de la misma manera. Lo desconozco.

I just learned from this post that the 1st astrophysics article by a Spanish astronomer was in 1966 and it was about polarization of the zodiacal light!

@ohdearz Amazing! Those filamentary structures resemble the Bfield structures we have observed in both galaxies. I wonder how coupled they are and their effect.

@RaphaelSkalidis @NASAHubble This is fantastic news and well deserved!

It is a great honor to have been selected as a Hubble Fellow this year! I am grateful to all the colleagues and mentors who have supported this effort. @NASAHubble #NHFP

I’m very excited to officially share that I’ll start as Associate Professor at @UofSC this Fall! Your hub for extragalactic magnetism 🧲🌀🌌 We will be looking for several new faculty to join us in the next few years, stay tuned for some news soon.

Nice explanation of the magnetic field pattern at the center of the black hole of our galaxy.

😃

@DrBrianKeating One can also spend hours looking at the dance of magnetic field lines across M51 ;) apod.nasa.gov/apod/ap210120.…

@TonyMroczkowski @lucadimascolo Can this be the observing mode while performing polarimetric observations?!?!

Well, here it is, after several years in the making: the first full look at the AtLAST design! arxiv.org/abs/2402.18645

@IBJIYONGI Strong ordered Bfields are spatial with the molecular gas in the galactic disk are already formed at z=2.6 nature.com/articles/s4158… Traceability of Bfields across the multiphase ISM: arxiv.org/abs/2311.06356 Merger activity amplifies Bfields: ui.adsabs.harvard.edu/abs/2023ApJ...…

@IBJIYONGI This work is focused on the physical properties of the dust grain sizes, alignment mechanisms, measurable polarization. Not much about the B-field, except that needs to be >uG (but we know that). Our other SALSA papers are more insightful about that topic.

New paper! Tram and I estimated the dust grain alignment mechanisms present in a galaxy using far-infrared polarimetric observations. Grains are aligned by B-fields, of course, and we now provide their size distributions. arxiv.org/abs/2402.18628
