How many active galaxies and QSOs will future Space Missions detect?

Averaged spectral energy distributions (SEDs) of active and starburst galaxies from the 12 micron sample in the Local Universe and Quasars, from an optically selected sample at a mean redshift =0.7, are built from optical/near-IR/far-IR (IRAS & ISO) photometric observations. These SEDs are then used to predict at various redshifts the number of Seyfert type 1 and type 2, starburst, normal galaxies, and quasars, that will be detected by future Space Missions dedicated to far-infrared and submillimeter astronomy, like SIRTF and Herschel. These predictions are then compared with the expected capabilities and detection limits of future deep far-IR surveys. Possible ways to identify AGN candidates on far-IR colour-colour plots for follow-up observations are then explored.Comment: accepted in Ap

The Effect of Promotion on Interest in Opening an Account at Bank Muamalat, Palu Branch

Purpose - The purpose of this study was to determine whether promotion has an effect on the interest of Islamic banking students in opening an account at the hammer branch of the muamalat bank and to find out how significant the effect of promotion is on student interest in opening an account at the hammer branch of the muamalat bank.Method - This study uses primary data, namely a questionnaire that uses a Likert scale as a calculation scale. The sample of this study was 485 students of the Faculty of Economics and Islamic Business IAIN Palu, Department of Islamic Banking from class 2016 to class 2018. To analyze the data, the authors used multiple linear regression methods and SPSS version 21. Result - Research result shows that the magnitude of the influence of the variable (X) on the variable (Y) is 0.388 or 38.8%. These results can provide an illustration that respondents (students) view that promotion can influence student interest in opening an account at a muamalat bank and promotion has a significant effect on student interest in opening an account at a muamalat bank. it can be seen that the promotion variable (X) has a value of tcount 3.783 t table 1.663 and has a significant value (sig) of 0.000 in the coefficients table with a value of α (significant level) 0.05. This means 0.000 0.05.Implications - This study is only limited to using data from several students in one university. Originality-. The difference with previous research is in the location and object under study.

DEIMOS Observations of WISE-Selected, Optically Obscured AGNs

While there are numerous criteria for photometrically identifying active galactic nuclei (AGNs), searches in the optical and UV tend to exclude galaxies that are highly dust obscured. This is problematic for constraining models of AGN evolution and estimating the AGN contribution to the cosmic X-ray and IR backgrounds, as highly obscured objects tend to be underrepresented in large-scale surveys. To address this, we identify potentially obscured AGNs using mid-IR color colors from the Wide-field Infrared Survey Explorer (WISE) catalog. This paper presents the results of optical spectroscopy of obscured AGN candidates using Keck DEIMOS, and their physical properties derived from these spectra. We find that a $W1-W2>0.8$ color criterion effectively selects AGNs with a higher median level of $E(B-V)$ extinction compared to the AGNs found in the SDSS DR7 survey. This optical extinction can be measured using SED modeling or by using $r-W1$ as a measure of optical to IR flux. We find that specific, targeted observations are necessary to find the most highly optically obscured AGNs, and that additional far-IR photometry is necessary to further constrain the dust properties of these AGNs.Comment: 20 pages, 25 figures, accepted by MNRA

The ultraviolet excess of quasars 3: The highly polarized quasars PKS 0736+017 and PKS 1510-089

Ultraviolet/optical/infrared spectrophotometry of the highly-polarized quasars (HPQ's) PKS 0736+017 and PKS 1510-089 is analyzed. A blazar continuum component like that in BL Lac objects (e.g. with violent variability, high polarization, and a steep power-law shape) contributes about half the visual light of 1510-089, and at least three-quarters of that in 0736+017. The remaining light has the same spectrum as normal (low-polarization) quasars, including an ultraviolet excess or blue bump, which is easily detected in the IUE spectra of 1510-089, and weakly detected in 0736+017. The line fluxes do vary, but not as much as the continuum. The ratios of the broad emission lines, and the Balmer continuum are normal in both quasars

Far-infrared properties of optically-selected quasars and Seyfert galaxies

Pointed IRAS observations and ground based observations are used to determine the infrared properties of optically selected galaxies and quasars. The use of complete, unbiased, optically selected samples means that statistical tests can be applied to probe the underlying properties of active galactic nuclei (AGNs). The near infrared to millimeter spectral energy distributions (SEDs) were studied of the CfA Seyfert galaxies, a well defined, unbiased sample of 25 Type 1 and 23 Type 2 Seyfert galaxies selected by optical spectroscopy. Data given show strong trends in the infrared SEDs. Strong evidence is also given that the infrared spectra of Seyfert 2 galaxies are dominated by thermal emission from warm dust, while nonthermal emission is more important in the spectra of quasars and luminous Seyfert 1 nuclei
