Morphological classification of local luminous infrared galaxies [PDF]

Astronomy & Astrophysics, 2016
We present an analysis of the morphological classification of 89 luminous infrared galaxies (LIRGs) from the Great Observatories All-sky LIRG Survey (GOALS) sample using non-parametric coefficients and compare their morphology as a function of wavelength. We rely on images obtained in the optical (B- and I-band) as well as in the infrared (H-band and 5.

A new multi‐messenger description of starburst galaxies emission: perspectives for neutrino and gamma‐ray observations

Astronomische Nachrichten, Volume 344, Issue 1-2, January-February 2023., 2023
Abstract Star‐forming and starburst galaxies (SBGs), which are well‐known cosmic‐ray (CR) reservoirs, are expected to emit gamma rays and neutrinos predominantly via hadronic collisions. In this work we analyze the 10‐year Fermi‐Low Energy Technique (LAT) spectral energy distributions of 13 nearby galaxies by means of a physical model that accounts for

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.

Sub-kpc star-formation law in the local luminous infrared galaxy IC 4687 as seen by ALMA [PDF]

, 2016
We analyze the spatially resolved (250 pc scales) and integrated star-formation (SF) law in the local luminous infrared galaxy (LIRG) IC4687. This is one of the first studies of the SF law on a starburst LIRG at these small spatial scales.

The Phanerozoic climate

Annals of the New York Academy of Sciences, Volume 1519, Issue 1, Page 7-19, January 2023., 2023
We review the long‐term climate variations during the last 540 million years (Phanerozoic Eon). We first summarize the geological and geochemical datasets available for reconstruction of long‐term climate variations. We then explore the main drivers of climate that appear to explain a large fraction of these climatic oscillations. The first is the long‐

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 ...

Chemical abundances in the dwarf galaxy NGC 4163 based on the nebular and auroral emission lines

Astronomische Nachrichten, Volume 343, Issue 9-10, November-December 2022., 2022
Abstract We constructed an oxygen abundance map and N/O ratio map of the unusually low excitation dwarf irregular galaxy NGC 4163 based on publicly available spectroscopy obtained by the MaNGA survey. We detected auroral emission line [O II]λλ$$ \lambda \lambda $$7320,7330 which allows us to measure chemical abundance by direct Te$$ {\mathrm{T}}_e ...
