An Extragalactic Widefield Search for Technosignatures with the Murchison Widefield Array

Chenoa D. Tremblay, Steven J. Tingay

It is common for surveys that are designed to find artificial signals generated by distant civilizations to focus on galactic sources. Recently, researchers have started focusing o…

PDRs4All. X. ALMA and JWST detection of neutral carbon in the externally irradiated disk d203-506: Undepleted gas-phase carbon

Javier R. Goicoechea, J. Le Bourlot, J. H. Black +26

The gas-phase abundance of carbon, x_C = C/H, and its depletion factors are essential parameters for understanding the gas and solid compositions that are ultimately incorporated i…

Halfway to the Peak: The JWST MIRI 5.6 micron number counts and source population

Leonid Sajkov, Anna Sajina, Alexandra Pope +9

We present an analysis of eight JWST Mid-Infrared Instrument (MIRI) 5.6 micron images with depths of ~0.1 uJy. We detect 2854 sources within our combined area of 18.4 square…

PDRs4All VIII: Mid-IR emission line inventory of the Orion Bar

Dries Van De Putte, Raphael Meshaka, Boris Trahin +135

Mid-infrared emission features probe the properties of ionized gas, and hot or warm molecular gas. The Orion Bar is a frequently studied photodissociation region (PDR) containing l…

Formation of the Methyl Cation by Photochemistry in a Protoplanetary Disk

Olivier Berné, Marie-Aline Martin-Drumel, Ilane Schroetter +53

Forty years ago it was proposed that gas phase organic chemistry in the interstellar medium was initiated by the methyl cation CH3+, but hitherto it has not been observed outside t…

PDRs4All. V. Modelling the dust evolution across the illuminated edge of the Orion Bar

M. Elyajouri, N. Ysard, A. Abergel +31

We study the emission of dust grains within the Orion Bar - a well-known, highly far-UV (FUV)-irradiated PDR. The Orion Bar because of its edge-on geometry provides an exceptional…
