Core-collapse supernova subtypes in luminous infrared galaxies [PDF]
Astronomy & Astrophysics, 2021 The fraction of core-collapse supernovae (CCSNe) occurring in the central regions of galaxies is not well constrained at present. This is partly because large-scale transient surveys operate at optical wavelengths, making it challenging to detect transient sources that occur in regions susceptible to high extinction factors.

A brief history of image sensors in the optical
Astronomische Nachrichten, Volume 344, Issue 8-9, October-November 2023., 2023 Image sensors, most notably the Charge Coupled Device (CCD), have revolutionized observational astronomy as perhaps the most important innovation after photography. Since the 50th anniversary of the invention of the CCD has passed in 2019, it is time to review the development of detectors for the visible wavelength range, starting with the discovery of

Energetic nuclear transients in luminous and ultraluminous infrared galaxies [PDF]
Astronomy & Astrophysics, 2022 Energetic nuclear outbursts have been discovered in luminous and ultraluminous infrared galaxies (U/LIRGs) at unexpectedly high rates. To investigate this population of transients, we performed a search in mid-IR data from the Wide-field Infrared Survey Explorer (WISE) satellite and its NEOWISE survey to detect and characterise luminous and smoothly ...

Spectroscopy of Luminous Infrared Galaxies [PDF]
Symposium - 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 ...

The star formation history of luminous infrared galaxies [PDF]
Astronomy & Astrophysics, 2006 We constrain the past star formation histories of a sample of 25 distant (z~0.7) luminous infrared galaxies (LIRGs) detected with the mid infrared cameras ISOCAM and MIPS onboard the ISO and Spitzer satellites. We use high resolution VLT-FORS2 spectroscopy in addition to a comprehensive library of 200,000 model optical spectra to derive Bayesian ...

Evolution of the ISM in luminous infrared galaxies [PDF]
Astronomy and Astrophysics, 2010 Molecules that trace the high-density regions of the interstellar medium may be used to evaluate the changing physical and chemical environment during the ongoing nuclear activity in (Ultra-)Luminous Infrared Galaxies. The changing ratios of the HCN(1-0), HNC(1-0), HCO+(1-0), CN(1-0) and CN(2-1), and CS(3-2) transitions were compared with the HCN(1-0 ...

The hyperluminous X‐ray source population
Astronomische Nachrichten, Volume 344, Issue 4, May 2023., 2023 Abstract We have recently published a catalog of 1843 candidate ultraluminous X‐ray sources (ULXs). This is the largest catalog of ULXs to date and was built by cross‐correlating recent serendipitous source catalogs from the XMM‐Newton, Swift, and Chandra observatories with a large sample of galaxies, primarily from HyperLEDA.
