A MUSE map of the central Orion Nebula (M 42) [PDF]

open access: yes, 2015
We present a new integral-field spectroscopic dataset of the central part of the Orion Nebula (M 42), observed with the MUSE instrument at the ESO VLT. We reduced the data with the public MUSE pipeline.

PDRs4All. II. JWST's NIR and MIR imaging view of the Orion Nebula [PDF]

open access: yesAstronomy & Astrophysics, 2023
The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypical highly irradiated dense photo-dissociation region (PDR). We investigate

Photoionized Herbig-Haro objects in the Orion Nebula through deep high-spectral resolution spectroscopy III: HH 514 [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2022
We analyze the physical conditions and chemical composition of the photoionized Herbig-Haro object HH 514, which emerges from the proplyd 170-337 in the core of the Orion Nebula.

Demographics of the M-star Multiple Population in the Orion Nebula Cluster [PDF]

open access: yesAstrophysical Journal, 2022
We present updated results constraining multiplicity demographics for the stellar population of the Orion Nebula Cluster (ONC, a high-mass, high-density star-forming region), across primary masses 0.08–0.7 M ⊙.

Small Protoplanetary Disks in the Orion Nebula Cluster and OMC1 with ALMA [PDF]

open access: yesAstrophysical Journal, 2021
The Orion Nebula Cluster (ONC) is the nearest dense star-forming region at ∼400 pc away, making it an ideal target to study the impact of high stellar density and proximity to massive stars (the Trapezium) on protoplanetary disk evolution.

The 3D Kinematics of the Orion Nebula Cluster: NIRSPEC-AO Radial Velocities of the Core Population [PDF]

open access: yesAstrophysical Journal, 2021
The kinematics and dynamics of stellar and substellar populations within young, still-forming clusters provide valuable information for constraining theories of formation mechanisms.

Binary Formation in the Orion Nebula Cluster: Exploring the Substellar Limit [PDF]

open access: yesAstrophysical Journal, 2021
We present results constraining the multiplicity of the very low mass stars and substellar objects in the Orion Nebula Cluster (ONC). Our sample covers primary masses 0.012–0.1 M ⊙ using archival Hubble Space Telescope data obtained with the Advanced ...

The NIKA polarimeter on science targets: Crab nebula observations at 150 GHz and dual-band polarization images of Orion Molecular Cloud OMC-1 [PDF]

open access: yesEPJ Web of Conferences, 2020
We present here the polarization system of the NIKA camera and give a summary of the main results obtained and performed studies on Orion and the Crab nebula.

Primordial Helium-3 Redux: The Helium Isotope Ratio of the Orion Nebula [PDF]

open access: yesAstrophysical Journal, 2022
We report the first direct measurement of the helium isotope ratio, 3He/4He, outside of the Local Interstellar Cloud, as part of science-verification observations with the upgraded CRyogenic InfraRed Echelle Spectrograph.

Photoionized Herbig–Haro objects in the Orion Nebula through deep high-spectral resolution spectroscopy – I. HH 529 II and III [PDF]

open access: yes, 2021
We present the analysis of physical conditions, chemical composition and kinematic properties of two bow shocks—HH 529 II and HH 529 III— of the fully photoionized Herbig-Haro object HH 529 in the Orion Nebula. The data were obtained with the Ultraviolet
