Unveiling the environment and faint features of the isolated galaxy CIG 96 with deep optical and HI observations
2018
Context. Asymmetries in atomic hydrogen (HI) in galaxies are often caused by the interaction with close companions, making isolated galaxies an ideal framework to study secular evolution. The AMIGA project has demonstrated that isolated galaxies show the lowest level of asymmetry in their HI integrated profiles compared to even field galaxies, yet some present significant asymmetries. CIG 96 (NGC 864) is a representative case reaching a 16% level. Aims. Our aim is to investigate the HI asymmetries of the spiral galaxy CIG 96 and what processes have triggered the star-forming regions observed in the XUV pseudo-ring. Methods. We performed deep optical observations at CAHA1.23m, CAHA2.2m and V…
Faint γ-ray sources at low redshift: the radio galaxy IC 1531
2018
We present amultiwavelength study of IC 1531 (z=0.02564), an extragalactic radio source associated with the γ -ray object 3FGL J0009.9-3206 and classified as a blazar of uncertain type in the Third Fermi-Large Area Telescope AGN catalog (3LAC). A core-jet structure, visible in radio and X-rays, is enclosed within a ~220 kpc wide radio structure. The morphology and spectral characteristics of the kiloparsec jet in radio and X-rays are typical of Fanaroff-Riley type I galaxies. The analysis of the radio data and optical spectrum and different diagnostic methods based on the optical, infrared, and γ -ray luminosities also support a classification as a low-power RG seen at moderate angles (θ = …
Fight against cancer in Italy: What patients, caregivers and healthy citizens think about care delivery from National Health System
2022
Objective: This survey aimed to analyse healthy citizens (HC), cancer patients and their caregivers (CP&CG) perception about cancer care among six different Italian regions. Methods: The survey for HC was conducted by a multinational market research institute (IPSOS) through a computer-assisted web interviewing system, using a dataset of people who had consented to be interviewed for previous studies. CP&CG were interviewed by patient advocates using paper questionnaires. Results: HC completed 1831 questionnaires between May and June 2019; CP&CG filled 1779 questionnaires between May and October 2019. 55% of all interviewees felt they were adequately informed about cancer, with …
El compromiso con la sustentabilidad en el activismo ecologista
2021
En este artículo se exponen los principales resultados de un estudio exploratorio del compromiso con la sostenibilidad de los activistas ecologistas. El análisis de las narrativas de los participantes, obtenidas a través de entrevistas semi-estructuradas de 7 activistas ecologistas muestra como su compromiso con la sostenibilidad se corresponde con el desarrollo de un enfoque ecosocial de la sostenibilidad que se descompone en un factor ambiental y un factor social que interrelacionan entre sí. También se relaciona con una identidad ambiental de conexión con la naturaleza; una pluralidad de identidades individuales como agentes de cambio y roles sociales (activistas, conservacionistas, cons…
The common sense model of illness self-regulation : a conceptual review and proposed extended model
2021
The common sense model of illness self-regulation outlines the dynamic processes by which individuals perceive, interpret, and respond to health threats and illness-related information. An extended version of the model is proposed, which specifies additional constructs and processes to explain how lay perceptions of health threats impact coping responses and health-related outcomes. The extended model provides detail on: (a) the mediating process by which individuals’ illness representations relate to illness outcomes through adoption of coping procedures; (b) how illness representations are activated by presentation of health-threatening stimuli; (c) behavioral and treatment beliefs as det…
La impugnación del despido colectivo
2022
El eje central de este estudio consiste en analizar la regulación normativa de la modalidad procesal de impugnación del despido colectivo, así como las principales dudas interpretativas que su aplicación genera. Con ello, se pretende, determinar si el legislador ha logrado el objetivo perseguido por la reforma del régimen jurídico del despido colectivo, a saber, una mayor seguridad jurídica, una menor ralentización del procedimiento, y, en consecuencia, la tan pretendida celeridad proclamada por la reforma y la concreción de la causa, y, por ende, una menor judicialización respecto de esta. Pues bien, en el capítulo primero, como paso previo necesario para conocer los elementos de la config…
Broad-band Spectral Evolution of Scorpius X-1 along its Color-Color Diagram
2007
We analyze a large collection of RXTE archive data from April 1997 to August 2003 of the bright X-ray source Scorpius X-1 in order to study the broadband spectral evolution of the source for different values of the inferred mass accretion rate by studying energy spectra from selected regions in the Z-track of its Color-Color Diagram. A two-component model, consisting of a soft thermal component interpreted as thermal emission from an accretion disk and a thermal Comptonization component, is unable to fit the whole 3--200 keV energy spectrum at low accretion rates. Strong residuals in the highest energy band of the spectrum require the addition of a third component that can be fitted with a …
23 GHz VLBI observations of SN 2008ax (Research Note)
2009
We report on phase-referenced 23 GHz Very-Long-Baseline-Interferometry (VLBI) observations of the type IIb supernova SN 2008ax, made with the Very Long Baseline Array (VLBA) on 2 April 2008 (33 days after explosion). These observations resulted in a marginal detection of the supernova. The total flux density recovered from our VLBI image is 0.8 ± 0.3 mJy (one standard deviation). As it appears, the structure may be interpreted as either a core-jet or a double source. However, the supernova structure could be somewhat confused with a possible close by noise peak. In such a case, the recovered flux density would decrease to 0.48 ± 0.12 mJy, compatible with the flux densities measured with the…
An X-ray characterization of the central region of the supernova remnant G332.5-5.6
2015
Aims. We present an X-ray analysis of the central region of supernova remnant (SNR) G332.5-5.6 through an exhaustive analysis of XMM-Netwon observations with complementary infrared observations. We characterize and discuss the origin of the observed X-ray morphology, which presents a peculiar plane edge over the west side of the central region. Methods. The morphology and spectral properties of the X-ray SNR were studied using a single full frame XMM-Netwon observation in the 0.3 to 10.0 keV energy band. Archival infrared WISE observations at 8, 12 and 24 μm were also used to investigate the properties of the source and its surroundings at different wavelengths. Results. The results show th…
Sub-milliarcsecond imaging of a bright flare and ejection event in the extragalactic jet 3C 111
2020
Context. Flares in radio-loud active galactic nuclei are thought to be associated with the injection of fresh plasma into the compact jet base. Such flares are usually strongest and appear earlier at shorter radio wavelengths. Hence, very long baseline interferometry (VLBI) at millimeter(mm)-wavelengths is the best-suited technique for studying the earliest structural changes of compact jets associated with emission flares. Aims. We study the morphological changes of the parsec-scale jet in the nearby (z = 0.049) γ-ray bright radio galaxy 3C 111 following a flare that developed into a major radio outburst in 2007. Methods. We analyse three successive observations of 3C 111 at 86 GHz with th…
