SUMMARY:SO Colloquium: Gravitational wave astrometry with the SKAO
DESCRIPTION:Pulsar timing array detection of a gravitational wave background represents a milestone in the field of gravitational wave astronomy. However\, the origin of such a signal is still a matter of intense debate: while supermassive black hole binaries formed as a result of galaxy mergers represent the most obvious candidate for the gravitational wave signal\, many «new Physics» models can potentially explain at least part of the detected background. In this colloquium I will review the current observational and theoretical status of the field\, addressing current issues and future challenges\, Moreover\, I will discuss how radio observations with the SKAO can contribute to this broader context\, and\, in particular\, I will focus on a possible background detection strategy that involves both pulsar timing array and gravitational wave astrometry. \nFecha: 06/03/2025 – 12:30Conferenciante: Dr. Nicola BellomoFiliación: Dipartimento di Fisica “Galileo Galilei”\, Universitá degli Studi di Padova\, Italy \n

SUMMARY:J-HERTz: J-PLUS Heritage Exploration of Radio Targets at z < 5
DESCRIPTION:In this talk\, I will present J-HERTz\, the J-PLUS Heritage Exploration of Radio Targets at z < 5\, a multi-wavelength catalog combining LoTSS DR2 radio data\, WISE infrared detections\, and J-PLUS DR3 optical narrow-band observations. Covering 2100 deg²\, J-HERTz includes nearly 500\,000 sources\, classified into galaxies\, QSOs\, and stars\, along with new photometric redshifts for objects without spectroscopy. \nA key discovery is a population of radio-loud galaxies with no ongoing nuclear activity\, many of which show large-scale radio emission (~185 kpc)\, suggesting they are AGN relics revealed at low radio frequencies. Using SED fitting from J-PLUS with CIGALE\, we analyze the link between radio-loudness\, stellar mass\, and star formation. Radio-loud galaxies tend to be massive and quenched\, while radio-quiet starbursts have much higher specific star formation rates. \nFor QSOs\, we find a bimodal distribution of radio-loud and radio-quiet populations\, with the radio-loud fraction increasing with redshift\, reaching ~20% at z = 3.5-4. Additionally\, J-HERTz identifies stars with radio emission\, which may be linked to coronal activity or exoplanet interactions\, though background contamination must be considered. \nBy combining optical\, IR\, and radio data\, J-HERTz provides new insights into AGN evolution\, jet activity\, and the nature of radio sources across cosmic time. I will discuss the implications of these findings and their connection to galaxy evolution. \nFecha: 11/03/2025 – 12:30Conferenciante: David Fernández GilFiliación: CEFCA\, Teruel\, España \n

SUMMARY:What Stops Star Formation in Isolated Dwarf Galaxies in the Most Underdense Cosmic Regions?
DESCRIPTION:The shallow potential wells of low-mass galaxies\, commonly known as dwarf galaxies\, make them highly susceptible to environmental effects\, often leading to the complete cessation of star formation. But is quenching solely driven by external forces in harsh environments\, or can dwarf galaxies also self-quench through mechanisms like strong stellar winds or supernova feedback\, independent of external influences? In this contribution\, I present our latest findings on a sample of isolated and quenched dwarf galaxies in the sparse environments of the cosmic web\, including voids and filaments. With no neighbors within a 1 Mpc radius\, these galaxies reside in environments where traditional quenching mechanisms—such as ram pressure stripping and tidal interactions—are negligible. Intriguingly\, some of these galaxies ceased forming stars 7 to 8 Gyr ago\, exhibiting star formation histories akin to dwarf galaxies in the dense cores of massive clusters like Virgo and Fornax. The existence of such galaxies in vastly different environments challenges conventional quenching paradigms and highlights the need to explore alternative mechanisms\, including internal feedback processes and distinct formation pathways. Understanding these processes alongside environmental effects is crucial for developing a more complete picture of star formation cessation in dwarf galaxies. \nFecha: 25/03/2025 – 12:30Conferenciante: Dr. Bahar BidaranFiliación: Dpto.

SUMMARY:Ciencia en palabras
DESCRIPTION:Peter Brook\, uno de los directores más influyentes del teatro contemporáneo\, decía que “lo inesperado no tiene límites”. Y así es.  Por ejemplo\, se puede encontrar la ciencia en lugares inesperados\, como los discursos de ingreso de la Real Academia Española (RAE). \nEstos textos son ensayos muy concretos sobre un tema y\, también\, son una instantánea de la sociedad\, del arte y de la ciencia en diferentes contextos históricos. \nEsta charla pretende ser una breve y entretenida reseña de esos discursos donde la ciencia pasa a través del prisma de la palabra de artistas y académicos. \nLa visión es la de una investigadora en astrofísica\, teatrera e … italiana\, que\, al equivocarse mucho en las palabras y consultar tanta veces la RAE\, ha encontrado mucha ciencia. La ciencia en las palabras de la RAE es una inesperada y inspiradora sorpresa que merece ser compartida. \nFecha: 27/03/2025 – 19:00Conferenciante: Sara CazzoliFiliación: Instituto de Astrofísica de Andalucía (IAA-CSIC) \n
