Hector Galaxy Survey: Falling in Between - Infalling Galaxies in the Midst of the Abell 3667 Merger
Oğuzhan Çakır, Matt Owers, Gabriella Quattropani +38
Whether cluster mergers enhance ram pressure stripping (RPS) and accelerate member galaxy evolution remains an open question. Here, we investigate galaxy populations in the nearby…
FIRST-PL: Commissioning the first visible photonic lantern spectrograph for sub-diffraction-limit astronomy on Subaru/SCExAO
Sebastien Vievard, Elsa Huby, Sylvestre Lacour +18
FIRST-PL (Fibered Imager foR a Single Telescope - Photonic Lantern) is a newly commissioned visible-light instrument on Subaru/SCExAO achieving spectroscopy below the diffraction l…
Empirical verification of principal mode orthogonality and relative phase calibration in photonic lanterns
Adam K. Taras, Barnaby R. M. Norris, Christopher Betters +5
The paper experimentally characterizes the principal modes of a photonic lantern using digital off‑axis holography, showing they are highly orthogonal and proposing ways to use thi…
Overcoming the low signal-to-noise problem for hybrid mode-selective photonic lantern-based wavefront correction using machine learning
Nathan K Long, Barnaby Norris, Daniel S Dahl +10
Hybrid mode-selective photonic lanterns transform an input complex point-spread function into several single-mode outputs, where a selected core feeds the fundamental mode to a pho…
Seidr update: photonic 'black magic' for high-contrast interferometry using kernel-nulling and photonic lanterns
Nathan K Long, Daniel S Dahl, Christopher H Betters +13
Seidr is a new interferometric beam combiner within the Asgard Suite, utilizing infrastructure common to the BIFROST instrument at the Very Large Telescope Interferometer. Seidr co…
Combining spectroscopy and wavefront control at deep contrast with photonic lanterns
Mona El Morsy, Olivier Guyon, Barnaby Norris +7
HWO aims to directly image objects orbiting Sun-like stars, using a 6-m telescope capable of high-contrast imaging () and spectroscopy to search for biosignatures in plan…
