Comparing the relation between star formation and galaxy mass in different environments [PDF]

open access: yes, 2009
Analyzing 24 mu m MIPS/Spitzer data and the [O II]3727 line of a sample of galaxies at 0.4 < z < 0.8 from the ESO Distant Cluster Survey (EDisCS), we investigate the ongoing star formation rate (SFR) and the specific star formation rate (SSFR) as a ...

AUGURAL TERRITORIES: On the Prophetic Organizing of the Mid‐range

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract In this article I introduce the concept of augural territories to theorize the urbanism that emerged during pandemic lockdowns. I draw on ethnographic research in Madrid to examine how community‐based responses—including mutual aid networks, food pantries and neighbourhood associations—disrupted the spatial and temporal logics of territorial ...

AEGIS: A Multi-wavelength Study of Spitzer Power-law Galaxies

open access: yes, 2010
This paper analyzes a sample of 489 Spitzer/IRAC sources in the Extended Groth Strip whose spectral energy distributions fit a red power law from 3.6 to 8.0 \micron. The median for sources with known redshift is =1.6.

Accountability and Hyperaccountability in Child Protection Scandals

open access: yesChild &Family Social Work, EarlyView.
ABSTRACT The number of child abuse–related deaths has decreased significantly in the United Kingdom over the past 50 years, but there remains public and political concern about the actual and perceived risk of child deaths, with resultant processes enacted to supervise child protection practice.

Innovative Strategies and Use of UAVs to Survey and Monitor Archaeological Sites in Conflict/Post Conflict Zones. The Case Study of the Fortified Citadel of Shahr-i Zohak in Bamiyan (Afghanistan) [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Although unmanned aerial vehicle (UAV) mapping and photogrammetry have become common and relatively accessible for surveying and mapping cultural heritage sites, conducting surveys to model sites in conflict/post conflict zones remains challenging.

The X-ray luminosity function of Active Galactic Nuclei in the redshift interval z=3-5

open access: yes, 2015
We combine deep X-ray survey data from the Chandra observatory and the wide-area/shallow XMM-XXL field to estimate the AGN X-ray luminosity function in the redshift range z=3-5.

Two Regimes of Waste and Value: ‘Post‐Disaster’ Landscapes in a New India

open access: yesDevelopment and Change, EarlyView.
ABSTRACT In this age of ‘disaster capitalism’, catastrophes are neither ‘natural’ nor ‘external’. They are political events mediating and vitally shaping the unequal and exploitative use of environmental resources. India's ‘post‐disaster’ landscapes at the turn of the new millennium powerfully demonstrate how visions of the new‐normal can be imposed in

Penetration ability and microhardness of infiltrant resin and two pit and fissure sealants in primary teeth with early enamel lesions

open access: yesScientific Reports, 2022
To determine the penetration depth and enamel microhardness (EMH) of an infiltrant resin and two fissure sealants in primary teeth with early enamel lesions. We randomly divided 174 sound teeth into six groups (n = 29): (1) phosphoric acid (PA) + Clinpro,

Selection and Mid-infrared Spectroscopy of Ultraluminous Star-Forming Galaxies at z~2 [PDF]

open access: yes, 2014
Starting from a sample of 24 \micron\ sources in the Extended Groth Strip, we use 3.6 to 8 \micron\ color criteria to select ultraluminous infrared galaxies (ULIRGs) at $z\sim2$.
