A Catalog of Point Sources Towards NGC 1333

I present a catalog of point source objects towards NGC 1333, resolving a wide variety of confusion about source names (and occasionally positions) in the literature. I incorporate data from optical to radio wavelengths, but focus most of the effort on being complete and accurate from J (1.25 um) to 24 um. The catalog encompasses 52 deg<RA<52.5 deg and 31 deg<Dec<31.6 deg. Cross-identifications include those from more than 25 papers and catalogs from 1994-2014, primarily those in wide use as origins of nomenclature. Gaps in our knowledge are identified, with the most important being a lack of spectroscopy for spectral types or even confirmation of youth and/or cluster membership. I fit a slope to the spectral energy distribution (SED) between 2 and 24 um for the members (and candidate members) to obtain an SED classification, and compare the resulting classes to those for the same sources in the literature, and for an SED fit between 2 and 8 um. While there are certainly differences, for the majority of the sources, there is good agreement.Comment: 34 pages, 7 figures. Accepted to AJ.

An X-ray and Infrared Survey of the Lynds 1228 Cloud Core

The nearby Lynds 1228 (L1228) dark cloud at a distance of ~200 pc is known to harbor several young stars including the driving sources of the giant HH 199 and HH 200 Herbig-Haro outflows. L1228 has been previously studied at optical, infrared, and radio wavelengths but not in X-rays. We present results of a sensitive 37 ks Chandra ACIS-I X-ray observation of the L1228 core region. Chandra detected 60 X-ray sources, most of which are faint (<40 counts) and non-variable. Infrared counterparts were identified for 53 of the 60 X-ray sources using archival data from 2MASS, Spitzer, and WISE. Object classes were assigned using mid-IR colors for those objects with complete photometry, most of which were found to have colors consistent with extragalactic background sources. Seven young stellar object (YSO) candidates were identified including the class I protostar HH 200-IRS which was detected as a faint hard X-ray source. No X-ray emission was detected from the luminous protostar HH 199-IRS. We summarize the X-ray and infrared properties of the detected sources and provide IR spectral energy distribution modeling of high-interest objects including the protostars driving the HH outflows.Comment: 38 pages, 7 tables, 8 figures; to appear in A

The NASA/IPAC Teacher Archive Research Program (NITARP)

NITARP, the NASA/IPAC Teacher Archive Research Program, partners small groups of largely high school educators with research astronomers for a year-long research project. This paper presents a summary of how NITARP works. Because NITARP has been running since 2009, and its predecessor ran from 2005-2008, there have been many lessons learned over the last 13 years, some of which are also discussed here. The most important of these include the following. Scientists must see their work with the educators on their team as a partnership of equals. Educators must be reminded often that they will not have command of all the information needed during their NITARP year, and that it is ok to ask lots of questions. NITARP teams need to be about 5 people: a mentor astronomer, a mentor teacher (who has been through the program before), and 3 new educators; larger or smaller teams just don’t work as well. Teams need to communicate regularly and frequently through their year

The NASA/IPAC Teacher Archive Research Program (NITARP)

NITARP, the NASA/IPAC Teacher Archive Research Program, partners small groups of predominantly high school educators with research astronomers for a year-long research project. This paper presents a summary of how NITARP works and the lessons learned over the last 13 years. The program lasts a calendar year, January to January, and involves three ~week-long trips: to the American Astronomical Society (AAS) winter meeting, to Caltech in the summer (with students), and back to a winter AAS meeting (with students) to present their results. Because NITARP has been running since 2009, and its predecessor ran from 2005-2008, there have been many lessons learned over the last 13 years that have informed the development of the program. The most critical is that scientists must see their work with the educators on their team as a partnership of equals who have specialized in different professions. NITARP teams appear to function most efficiently with approximately 5 people: a mentor astronomer, a mentor teacher (who has been through the program before), and 3 new educators. Educators are asked to step into the role of learner and develop their question-asking skills as they work to develop an understanding of a subject in which they will not have command of all the information and processes needed. Critical to the success of each team is the development of communication skills and fluid plan of action to keep the lines of communication open. This program has allowed more than 100 educators to present more than 60 total science posters at the AAS.Comment: Accepted by refereed conference proceedings for RTSRE 201

La Integració a al-Andalus dels territoris a ponent del Llobregat

Més enllà de les àrees de Lleida i Tortosa, incorporades a l'àmbit cristianofeudal a mitjan segle XII, la presència de l'estat andalusí a la resta de les terres avui catalanes ha estat, salvant comptades excepcions, tradicionalment negligida per la historiografia. Per al territori que ens ocupa, les dades que ens ofereixen les fonts documentals sobre això són més que limitades, mentre que el coneixement que tenim del registre arqueològic vinculat als segles VIII i IX és encara molt precari. Davant d'això, l'estudi de la toponímia esdevé un element imprescindible per guiar aquesta necessària pràctica arqueològica. Així, al costat d'arabismes evidents, com ara els vinculats a ribat (s) o almúnies, noves línies de recerca proposen la identificació dels topònims palatium i pharus amb establiments creats a partir de la conquesta musulmana. Per altra banda, en aquest text també es planteja una relectura del jaciment d'Olèrdola com un enclavament en funcionament durant aquest mateix període.Besides the Lleida and Tortosa areas, which became feudal domains in mid 12th century, the presence of Andalusian state has been often neglected by historiography. For the territory we are focusing on, the study of toponymy becomes essential to guide this necessary archaeological practise because of the poor data from documentary sources and the precarious stage of the archaeological register of the 8th and 9th centuries. Besides the obvious arabic expressions such as those linked to ribat (s) or almúnies, new lines of research propound the identification of the toponyms palatium and pharus with settlements founded during the muslim conquest. By the other hand, also in this text a new interpretation of the Olèrdola site as an active settlement during that period is proposed

Els Inicis de l'edat mitjana (segles VIII-IX) al Penedès i el Baix Llobregat: una aproximació arqueològica

Com en períodes anteriors, l'estudi de l'alta edat mitjana a Catalunya, especialment durant els segles anteriors a la profusió de documents vinculats a l'època carolíngia i comtal, permet poques aproximacions plantejades des de fora de la pràctica arqueològica. Així succeeix als territoris situats immediatament a ponent del Llobregat, els quals majoritàriament no passaran a incorporar-se a l'òrbita comtal fins a inicis del segle X. Aquest text pretén contribuir, a partir de dades ja conegudes i mitjançant la comparació amb paral·lels propers, a precisar el context cronològic de certs elements i estructures vinculats al registre arqueològic i que pensem que poden ubicar-se entre els segles VIII i IX. Així mateix, es vol fer una revisió de determinades construccions arquitectòniques, com són temples i fortificacions, per als quals es proposen algunes hipòtesis fundacionals.As in former periods, the study of the early middle ages in Catalonia allows few approaches brought up out of the archaeological practice, specially during the centuries before the profusion of documents linked to the Carolingian and county periods. This happens in the territories located westward of Llobregat river, which mostly will not join the county field until the beginning of the 10th century. Taking the already known data as a starting point and by means of a comparison with near parallel cases, this text intends to contribute to the determination of the chronological context of certain elements and structures linked to the archaeological record, which can be dated between the 8th and 9th centuries. Likewise, this text pretends a revision of some architectural constructions, such as temples and fortifications for which some foundational hypotheses are proposed

Els "Palatia" Septimans : indicis de l'organització terriorial andalusina al nord dels Pirineus

La presència de l'estat andalusí en terres septimanes ha estat, salvant comptades ocasions, tradicionalment negligida per la historiografia. En aquest text, tot aplicant una línia de recerca contrastada a Catalunya Vella que identifica els topònims derivats de palatium amb una primerenca xarxa d'establiments creats a partir de la conquesta islàmica, pretenem donar una primera visió de quin fou l'abast de l'organització territorial d'aquest estat al nord dels Pirineus. L'estudi de les fonts documentals i de la toponímia conservada ens permet veure com aquests topònims mostren unes pautes de dispersió coherents, alhora que es concentren sense excepcions a la meitat meridional de la SeptimàniaPresence of Andalusian State in Septimania has been traditionally neglected, with few exceptions, by historiography. In this text, we try to offer a view of the territorial organisation of the Andalusian State at the north of the Pyrenees by means of a line of research, contrasted in Catalunya Vella, that identifies the toponyms derived from palatium with a primitive network of settlements built during the Islamic conquest. The study of documentary and toponymic sources reveals that these toponyms show the guidelines of a logical spread, always concentrated in southern Septimani
