The SL2S Galaxy-scale Lens Sample. V. Dark Matter Halos and Stellar IMF of Massive Early-type Galaxies out to Redshift 0.8

, 2014
We investigate the cosmic evolution of the internal structure of massive early-type galaxies over half of the age of the Universe. We perform a joint lensing and stellar dynamics analysis of a sample of 81 strong lenses from the SL2S and SLACS surveys ...

Effect of Prudential Policies on Sovereign Bond Markets: Evidence From the ASEAN‐4 Countries

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper examines the effects of prudential policies on the sovereign vulnerability of ASEAN‐4 countries. We measure sovereign vulnerability within the network connectedness of sovereign bonds between ASEAN‐4 countries (Indonesia, Malaysia, the Philippines and Thailand) and six other countries (the US, the UK, the European Union, China ...

Simulating a White Dwarf-dominated Galactic Halo

, 2003
Observational evidence has suggested the possibility of a Galactic halo which is dominated by white dwarfs (WDs). While debate continues concerning the interpretation of this evidence, it is clear that an initial mass function (IMF) biased heavily toward

What Role Do Finance Ministers Play in Political Business Cycles? Evidence‐Based on a New African Dataset

International Journal of Finance &Economics, EarlyView.
ABSTRACT This study investigates how the personal characteristics of finance ministers influence political budget cycles in Africa. Using a new dataset covering 300 finance ministers across 23 countries from 1980 to 2020, we find that political budget cycles primarily take the form of increased government consumption during election years.

First Detection of CO Isotopologues in a High-redshift Main-sequence Galaxy: Evidence of a Top-heavy Stellar Initial Mass Function

The Astrophysical Journal
Recent observations and theories have presented a strong challenge to the universality of the stellar initial mass function (IMF) in extreme environments. A notable example has been found for starburst conditions, where evidence favors a top-heavy IMF, i.

Mass-loss and expansion of ultra compact dwarf galaxies through gas expulsion and stellar evolution for top-heavy stellar initial mass functions

, 2010
(abridged) The dynamical V-band mass-to-light ratios of ultra compact dwarf galaxies (UCDs) are higher than predicted by simple stellar population models with the canonical stellar initial mass function (IMF).

Financial Literacy, Financial Development and Economic Growth

International Journal of Finance &Economics, EarlyView.
ABSTRACT While significant progress has been made in exploring the importance of financial literacy, its impact on economic growth and financial development from a macroeconomic point of view remains thinly understood. This paper provides fresh evidence on the relationship between financial literacy, financial development and economic growth.

The Impact of Changes in Real Income and the Real Effective Exchange Rate on Trade in Goods and Services

International Journal of Finance &Economics, EarlyView.
ABSTRACT We use foreign trade data on both imports and exports of goods and services among a group of 15 advanced economies to determine the incomes and price elasticities of demand for exports and imports of goods, services and goods and services combined in the long run.

Temporal Evolution of Sunspot Groups and Increase in the Open Flux during Solar Maximum in Cycle 24

The Astrophysical Journal
The evolution of the global solar magnetic field directly impacts the interplanetary magnetic field (IMF). During the solar maximum of Cycle 24, the monthly averaged IMF strength doubled over five Carrington rotations (CRs) in late 2014.
