WEBB ESTÁ TENIENDO PROBLEMAS 🛰 🔭

El instrumento NIRISS, cuya tarea es estudiar la composición de exoplanetas y galaxias lejanas, ha mostrado errores de comunicación y actualmente se encuentra fuera de servicio. Los equipos trabajan por traerlo de vuelta.

Are you into JWST exoplanet data analysis? Are you into NIRISS/SOSS?

In a set of papers today, we tell a beautiful story of how we figured out how light is dispersed in NIRISS/SOSS so well that we can predict trace positions *and* wavelength solutions for virtually any target.

Exoplanet WASP-96 b (NIRISS Transmission Spectrum)

new results from the jwst exoplanet ers program on arxiv! the takeaways? 👀

JWST/NIRISS is ✨sick✨ for bright targets. here's a light curve to prove it & yes you're reading that rms scale right: 5 (!!) ppm over an hour 😱

arxiv.org/abs/2301.08192

Kazumasa Ohno: JWST MIRI phase curve of the hazy sub-Neptune GJ1214b is large, suggesting high metallicity armosphere.

But the MIRI transmission spectrum suggests a flat line. Need further obs (e.g. NIRISS G395H)...but have to wait for their paper to see what they detect!

No hay buenas noticias para el #JWST el Near Infrared Imager and Slitless Spectrograph (NIRISS), se ha desconectado.
El NIRISS realiza espectroscopia en atmósferas de exoplanetas, entre otras cosas.
Esperemos pronto este en línea.

Os astrônomos descobriram o oxigênio mais antigo da história do universo e veja também que o James Webb está com problema no NIRISS!!!

O OXIGÊNIO MAIS DISTANTE DO UNIVERSO E UM NOVO PROBLEMA COM O JAMES WEBB - youtu.be/VHy4IE3uVx0

C'est le mode AMI du JWST avec le filtre NIRISS. Un bel objet ce télescope spatial décidément...
On le teste ici avec un système déjà bien connu, notamment observé par ALMA, dont voici une image avec un gros plan sur PDS70C, une de ses 2 exoplanètes connues :

NGDEEP is designed to constrain feedback mechanisms in low-mass galaxies across cosmic time. To do this, it's observing the Hubble Ultra Deep Field with deep NIRISS slitless spectroscopy (we call this NGDEEP-NIS) and the HUDF parallel field 2 with deep NIRCam imaging (NGDEEP-NRC)
