Journal Article
Davies, R., Shimizu, T., Pereira-Santaella, M., Alonso-Herrero, A., Audibert, A., Bellocchi, E., Boorman, P., Campbell, S., Cao, Y., Combes, F., Delaney, D., Díaz-Santos, T., Eisenhauer, F., Esparza Arredondo, D., Feuchtgruber, H., Förster Schreiber, N. M., Fuller, L., Gandhi, P., García-Bernete, I., García-Burillo, S., …Zhang, L. (2024). GATOS: missing molecular gas in the outflow of NGC 5728 revealed by JWST. Astronomy & Astrophysics, 689, Article A263. https://doi.org/10.1051/0004-6361/202449875

The ionisation cones of NGC 5728 have a deficit of molecular gas based on millimetre observations of CO (2-1) emission. Although photoionisation from the active nucleus may lead to suppression of this transition, warm molecular gas can still be prese...

MIDIS: Unveiling the Role of Strong Hα Emitters During the Epoch of Reionization with JWST (2024)
Journal Article
Rinaldi, P., Caputi, K. I., Iani, E., Costantin, L., Gillman, S., Perez Gonzalez, P. G., Östlin, G., Colina, L., Greve, T. R., Nørgard-Nielsen, H. U., Wright, G. S., Álvarez-Márquez, J., Eckart, A., García-Marín, M., Hjorth, J., Ilbert, O., Kendrew, S., Labiano, A., Le Fèvre, O., Pye, J., …Dayal, P. (2024). MIDIS: Unveiling the Role of Strong Hα Emitters During the Epoch of Reionization with JWST. Astrophysical Journal, 969(1), 12. https://doi.org/10.3847/1538-4357/ad4147

By using an ultradeep JWST/MIRI image at 5.6 μm in the Hubble eXtreme Deep Field, we constrain the role of strong Hα emitters (HAEs) during “cosmic reionization” at z ≃ 7-8. Our sample of HAEs is comprised of young (<35 Myr) galaxies, except for one...

Astrophysical Journal Supplement, 272(1), Article 19. https://doi.org/10.3847/1538-4365/ad3948

The James Webb Space Telescope (JWST) North Ecliptic Pole (NEP) Time-domain Field (TDF) is a >14′ diameter field optimized for multiwavelength time-domain science with JWST. It has been observed across the electromagnetic spectrum both from the groun...

The first spectroscopic IR reverberation programme on Mrk 509 (2024)
Journal Article
Mitchell, J. A. J., Ward, M. J., Kynoch, D., Santisteban, J. V. H., Horne, K., Pott, J. .-U., …Winkler, H. (2024). The first spectroscopic IR reverberation programme on Mrk 509. Monthly Notices of the Royal Astronomical Society, 529(4), 4824-4839. https://doi.org/10.1093/mnras/stae790

Near IR spectroscopic reverberation of Active Galactic Nuclei (AGN) potentially allows the infrared (IR) broad line region (BLR) to be reverberated alongside the disc and dust continua, while the spectra can also reveal details of dust astro-chemistr...

Deconvolution of JWST/MIRI Images: Applications to an Active Galactic Nucleus Model and GATOS Observations of NGC 5728 (2024)
Journal Article
Leist, M. T., Packham, C., Rosario, D. J. V., Hope, D. A., Alonso-Herrero, A., Hicks, E. K. S., …Shimizu, T. (2024). Deconvolution of JWST/MIRI Images: Applications to an Active Galactic Nucleus Model and GATOS Observations of NGC 5728. Astronomical Journal, 167(3), Article 96. https://doi.org/10.3847/1538-3881/ad1886

The superb image quality, stability, and sensitivity of JWST permit deconvolution techniques to be pursued with a fidelity unavailable to ground-based observations. We present an assessment of several deconvolution approaches to improve image quality...
