Candidates for Substellar Members of the Orion Nebula Cluster from JWST/NIRCam
The Astronomical JournalIn 2022, the James Webb Space Telescope (JWST) obtained 1–5 μ m images of the center of the Orion Nebula Cluster (ONC). I have analyzed these data in an attempt to search for substellar members of the cluster. Using a pair of color–color diagrams, I have

Nested shells reveal the rejuvenation of the Orion-Eridanus superbubble [PDF]
, 2015 The Orion-Eridanus superbubble is the prototypical superbubble due to its proximity and evolutionary state. Here, we provide a synthesis of recent observational data from WISE and Planck with archival data, allowing to draw a new and more complete ...

NEAR-INFRARED VARIABILITY IN THE ORION NEBULA CLUSTER [PDF]
, 2015 Using UKIRT on Mauna Kea, we have carried out a new near-infrared J, H, K monitoring survey of almost a square degree of the star-forming Orion Nebula Cluster with observations on 120 nights over three observing seasons, spanning a total of 894 days.

Distribution of Dust in the Orion Nebula [PDF]
Symposium - International Astronomical Union, 1974 The distribution of the dust is found by comparing 3-cm brightness temperatures, Hα surface brightness, and Hβ surface brightness. The dust is probably mixed with the gas. The Balmer radiation originates in front of the dark bay.

The area around the Orion Nebula observed in the CO (J = 1- 0) transition [PDF]
, 1980 An area 1 deg2 around the Orion Nebula has been surveyed with a 2.6 km s-1 wide single-channel receiver. The map shows considerable structure in the east including a bright spot 24' (2.8 pc) from the main CO ...

Large Area Mapping at 850 Microns. V. Analysis of the Clump Distribution in the Orion A South Molecular Cloud [PDF]
, 2006 We present results from a 2300 arcmin^2 survey of the Orion A molecular cloud at 450 and 850 micron using the Submillimetre Common-User Bolometer Array (SCUBA) on the James Clerk Maxwell Telescope.

A nebular analysis of the central Orion Nebula with MUSE [PDF]
, 2015 A nebular analysis of the central Orion Nebula and its main structures is presented. We exploit MUSE integral field observations in the wavelength range 4595-9366 \r{A} to produce the first O, S and N ionic and total abundance maps of a region spanning 6'

Gravitational collapse of the OMC-1 region [PDF]
, 2017 We have investigated the global dynamical state of the Integral Shaped Filament in the Orion A cloud using new N$_2$H$^+$ (1-0) large-scale, IRAM30m observations.

Gas absorption and dust extinction towards the Orion Nebula Cluster [PDF]
, 2016 We characterise the relation between the gas and dust content of the interstellar medium towards young stellar objects in the Orion Nebula Cluster. X-ray observations provide estimates of the absorbing equivalent hydrogen column density N_H based on ...
