The authors' main claim We suggest that these objects are young Supernova Remnants, with bright and broad \ha\ emission powered by the interaction between the SN ejecta and dense circumstellar material.

The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; .

We present results from a systematic search for broad ($\geq$ 400 \kms) \ha\ emission in Integral Field Spectroscopy data cubes of $\sim$1200 nearby galaxies obtained with PMAS and MUSE. We found 19 unique regions that pass our quality cuts, four of which match the locations of previously discovered SNe: one Type IIP, and three Type IIn, including the well-known SN 2005ip. We suggest that these objects are young Supernova Remnants, with bright and broad \ha\ emission powered by the interaction between the SN ejecta and dense circumstellar material. The stellar ages measured at the location of these SNR candidates are systematically lower by about 0.5 dex than those measured at the location of core collapse SNe, implying that their progenitors might be shorter lived and therefore more massive than a typical CC SN progenitor. The methods laid out in this work open a new window into the study of nearby SNe with Integral Field Spectroscopy.

The paper
Original abstract

We present results from a systematic search for broad ($\geq$ 400 \kms) \ha\ emission in Integral Field Spectroscopy data cubes of $\sim$1200 nearby galaxies obtained with PMAS and MUSE. We found 19 unique regions that pass our quality cuts, four of which match the locations of previously discovered SNe: one Type IIP, and three Type IIn, including the well-known SN 2005ip. We suggest that these objects are young Supernova Remnants, with bright and broad \ha\ emission powered by the interaction between the SN ejecta and dense circumstellar material. The stellar ages measured at the location of these SNR candidates are systematically lower by about 0.5 dex than those measured at the location of core collapse SNe, implying that their progenitors might be shorter lived and therefore more massive than a typical CC SN progenitor. The methods laid out in this work open a new window into the study of nearby SNe with Integral Field Spectroscopy.

What this paper does with the arXiv papers it cites

Each citing sentence is taken from the citing paper's LaTeX source and typed by Pith's classifier. A label appears at probability 0.8 or more (0.95 for support), a contest at 0.7 or more; the quoted words are the citing authors'. How each label was checked · JSON

  • This survey has been running for 11 semesters (P95-P106) with the focus of obtaining IFS of SN host galaxies, each semester with a different science focus including among others: hosts of SNe that showed strong sodium absorption lines in their spectra indicating the presence of large amounts of dust; hosts of SNe discovered by the ASASSN-SN survey to study SN rates as a function of local environment [ref] ; SN hosts with low surface brightness [ref] ; hosts of SNe included in the Carnegie Supernova Project (CSP; [ref] ) sample.

  • Although they are rare events, occurring once or twice per century in a typical galaxy, SNe are essential to understanding the chemical evolution of the Universe [ref] and the injection of energy into the interstellar medium [ref] .
