Decomposition of the central structure of NGC 2273 in the NIR: A case study

open access: yesAstronomische Nachrichten, Volume 344, Issue 10, December 2023., 2023
Abstract The Seyfert 2 galaxy NGC 2273 is a prime target to explore how active nuclei can be fed. It has a star‐forming innermost nuclear ring with a radius of 0.33kpc from where material may be funneled to the supermassive black hole in its center. In this article, we discuss high‐resolution adaptive optics aided JHKs images of NGC 2273 taken with the

Missing Giants: Predictions on Dust-obscured Galaxy Stellar Mass Assembly Throughout Cosmic Time

open access: yesThe Astrophysical Journal, 2023
Due to their extremely dust-obscured nature, much uncertainty still exists surrounding the stellar mass growth and content in dusty, star-forming galaxies (DSFGs) at z > 1. In this work, we present a numerical model built using empirical data on DSFGs to

Submillimetre surveys: The prospects for Herschel [PDF]

open access: yes, 2009
Using the observed submillimetre source counts, from 250-1200 microns (including the most recent 250, 350 and 500 micron counts from BLAST), we present a model capable of reproducing these results, which is used as a basis to make predictions for ...

Ultra wide‐field infrared astronomy in Antarctica

open access: yesAstronomische Nachrichten, Volume 344, Issue 8-9, October-November 2023., 2023
The science enabled by the deep and high‐cadence survey that will be performed by the Vera Rubin Observatory has led to an increase of survey and follow‐up capabilities around the world. The infrared, has however, not match this growth due to the challenges caused by the atmospheric and the cost of large detector arrays.

Spectroscopy of Luminous Infrared Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1999
A review of recent optical and infrared spectroscopic results on luminous infrared galaxies is presented. The main emphasis is on the ultraluminous objects. Possible correlations with infrared luminosity are identified. These results are used to constrain the nature of the dominant energy source in luminous infrared galaxies, and to test whether these ...

Luminous and Obscured Quasars and Their Host Galaxies

open access: yesFrontiers in Astronomy and Space Sciences, 2018
The most heavily-obscured, luminous quasars might represent a specific phase of the evolution of the actively accreting supermassive black holes and their host galaxies, possibly related to mergers.

GOALS-JWST: Unveiling Dusty Compact Sources in the Merging Galaxy IIZw096

open access: yesThe Astrophysical Journal Letters, 2022
We have used the Mid-InfraRed Instrument (MIRI) on the James Webb Space Telescope (JWST) to obtain the first spatially resolved, mid-infrared images of IIZw096, a merging luminous infrared galaxy (LIRG) at z = 0.036.

Quasars and Ultraluminous Infrared Galaxies: At the Limit? [PDF]

open access: yes, 1998
We have detected the host galaxies of 16 nearby, radio-quiet quasars using images obtained with the Near-Infrared Camera and Multi-Object Spectrometer (NICMOS).
